On kapotasana

Well, I'm working on kapotasana in mysore practice, so this post starts off with a self-practice video from Claudia, showing some first attempts at kapo and Supta Vajrasana. But first, if you're not familiar, the monster pose comes fairly early on in the Intermediate Series. Here's an image of Guruji helping Graeme Northfield into the pose (1982):
So, here's Claudia's attempt. Not a disaster, as she says, but the first step in the journey. You can see, though, how little lift to the chest there is in both these positions. Interestingly, there is quite a bit of ashtanga-blogging on the subject. For instance, Yoga in the Dragon's Den:
Kapotasana teaches us something about navigating the sufferings of daily life as well. Whether we like it or not, life throws unpleasant things at us, things that we can't just wish away or depend on others to take care of. We can choose to play into the drama that these things tend to evoke in our minds, and make the suffering bigger and badder than it needs to be; or we can do what needs to be done, breath, and go through what needs to be gone through with fortitude and hopefully, grace.

The Ashtanga 'jump back': Some instructional videos

Loved David Garrigues' Asana Kitchen on jumping back. He points out: the hands are way in front of your hips so there's no issue with hips fitting through; your weight is leaning back; energy galvanizes towards your center, knees get sucked towards you; you're going to create a very decisive move -- all of the sudden you're going to strike!

And here's a promotional clip for a little $4 download with the graceful Maria Villella. The clip shows her four steps to the jump back move although the whole video has lots of training exercises for pulling these moves off. The four steps: 1) pull knees into chest, plant the hands and lift; (2) lift it all the way up into "pendulum pose" (lolasana) -- yeah easy; (3) bend elbow to 90 while keep knees tucked; (4) kick the legs back to chat.

And there's this breakdown from Kino, taking it step by step.

Slowly, slowly ...

Some parents deride Ashtanga yoga in the schools as 'Hindu indoctrination'

Stories like this pop up from time to time, but it's still surprising to hear that some people are so afraid of other cultures, that they have a knee-jerk reaction. The HuffPo reports that some (Christian) parents are objecting to their kids being taught yoga in school because they are nothing more than "indoctrination" into Hinduism. This is probably partly because the program is funded by the Mysore-based Jois Foundation. As The Confluence Countdown points out, this is happening in Encinitas, CA, which is just about ground zero for Ashtanga in America, what with Tim Miller's Ashtanga Yoga Center and the Jois Yoga Shala, and I'm sure plenty of other yoga.

Now on Facebook.

Check out on Facebook at www.facebook.com/NorthBayAshtanga for more rapid updates on classes, Ashtanga videos and some in-depth content. Connect to other ashtangis there. .... See you on Facebook! Trying to generate some quick "likes" so give it a click.

Back on Sundays plus wrist relief

Been away the past few Sundays due to holiday travel and what-not, but I plan to be back at Studio Ganesha on the Sebastopol Plaza, Sundays at 11:00 for the foreseeable future (except the end of January for Tim Miller's Primary Teacher Training in Tulum). So hope to see you then. Johnny Smith is away Sunday, 12/9, hanging with Tim in Encinitas, and Ann Austin will be leading Primary Series at Westside Yoga Studio, at 8:00 a.m. Johnny is back the following week. I've been struggling with wrist problems (tendonitis?) for some months now, so check out this helpful articles from Yoga International -- Wrist Relief
The following asanas will help to develop mobility and strength in the shoulders and upper back to minimize nerve compression and stress on the smaller joints. In all of these poses, the upper trapezius muscles (which attach at the base of the skull and run down the neck to attach at the clavicles) should feel like they are releasing down the back, so that there is no congestion near the base of the neck, and the sides of the neck are free to lengthen. This aids in counteracting the imbalances of the typical slumped forward posture many of us assume in front of the computer, in which the shoulders are pulled forward and down, the tops of the trapezius muscles become hard and creep up toward the skull, and the head projects forward.

Yoga Sutra II.35

ahimsa pratisthayam tat sannidhau vaira tyagaha

In the presence of one who is established in nonviolence enmity is abandoned.

Hariharananda says violent thoughts have to be rooted out through dharana, fixing mind, which perfects yamas and niyamas. this shows that the later limbs deepen the earlier limbs, perfecting the yamas and making asana faultless.

Sharath in conference: Bandhas, and not sweating the details

Claudia has conference notes from DC-based teacher Megan Riley from Mysore. Here, Sharath field questions on the bandhas, what makes a good student, and how to handle all the little bits of Ashtanga like jump-backs and moving into standing poses. Here's what I picked up as key:
Bandhas take time—there is no quick one month certificate for Mula Bandha. Bandhas will help the asanas to develop energy inside us and bring stability to the body and mind. Some asanas are also good for developing the bandhas. Navasana, Utpluthih, and lifting up in our jumpbacks help us to strengthen the bandhas. This is why he makes us do them longer in led practices. Also, he added, it is fun for him.
The first question he took from students was what jumping back in Suryanamasakara A and B should look like. Sharath said to just do it—straight legs, bent legs, doesn’t matter. Another asana question asked was whether we should hop or simply step into our standing postures from Samasthitih. Again, Sharath said this doesn’t matter much. The vinyasa is important but using straight legs versus crossed legs, stepping or hopping, is not so important as long as the student has the correct vinyasa.
What makes a good student? Sharath said this question was difficult. A good student wants to learn yoga for self transformation. He or she doesn’t have any desire, only to get enlightened. Pattabhi Jois didn’t learn this to become famous. We do not need to be Brahmin or go through a ceremony. It doesn’t automatically make us enlightened. We can reach enlightenment without it. This is his karma. He was born in India and this is what he does. At the end of the day, it’s our own karma. To be human, that is our duty. Don’t be like an animal. Protect Dharma (truth) and Dharma will protect you. Just doing asanas is not enough. We have to be more responsible and think of more than just ourselves. This is a 24 hour practice.

Ashtanga Yoga - Practice and philosophy

Here's the current flier for my class, designed by my wife, the talented Amy Koman.

Jungle animal jumping through

I like David Garrigues' teaching on jumping through in the Ashtanga vinyasa. It's all about the crouch and springing forward. In this video he offer four options, from stepping it through, to using blocks, to the full jump-through. It's about gathering leg-hip energy with the crouch and then releasing that energy forward - woosh! We worked on this a bit in my class today, which btw, is Sundays 11:00 am at Yoga Studio Ganesha.

Richard Freeman dives in deep

British Ashtanga blogger Grimmly attended a full five-day workshop with the extraordinary Richard Freeman and has this excellent report. If you have taken classes with Richard before, much of this resonates as familiar. Start with posture and the prana/apana movements:
-frount of armpit up back and out -Bankers pose- exaggerates the patters of the yoga postures, prana and apana.. -there's a tendency to shut down the opposite pattern, pinching the shoulder blades together, closing the kidney wings -to avoid that we keep the exaggeration of the prana pattern, -we drop the coccyx, and float the shoulder blades apart slightly, allowing the floating ribs to spread, the pattern of apana returning -we get both patterns simultaneously, strong, each one stronger because of it's opposite
As Grimmly says: "Much of Richard'ss pranayama practice/teaching seems to inform his approach to asana, just as his approach to asana, the keen attention to alignment, informs his approach to pranayama." His notes are really very detailed, so they're worth a read, especially on the palate and the link to mula bandha. I appreciated his closing thoughts:
I really wanted to communicate this focus on the gaze/breath/ palate/release/bandha connection with the prana and apana model as it's key to Richards teaching. It doesn't matter the posture, any asana will do, it doesn't have to be fancy, the first half of primary will give you plenty to be going on with. An advanced practice doesn't begin with pasasana or kapo or vasisatasana it begins with ekam and dve ...if we attend to the breath. And it's because a pranayama practice can inform our asana practice that it may be worth considering beginning a simple, formal pranayama practice.

New Ashtanga Class: Sundays at 11 am in Sebastopol

(Photo by Lena Gardelli)

I'm starting up a new Ashtanga Yoga class at Yoga Studio Ganesha, Sundays at 11. The studio is right on the Plaza, so do a little shopping at the Farmer's Market before class. Here's my official description of the class:

Ashtanga yoga is known as a challenging yoga practice, but it is much more than that. The primary series presents an incredibly logical and opening sequence of poses, from standing to forward bends and hip openers, backbends and meditative postures. Underlying all of this is the yoga philosophy of Patanjali's Yoga Sutras, the path to liberation. Come learn or practice the Primary Series, coupled with a short discussion of the Sutras.
The emphasis is definitely on the practice: moving with the breath through the Primary Series sequence. But my practice is clearly informed by the underpinnings of the seminal text, Patanjali's Yoga Sutras, which teach the process of concentration and meditation that lead to samadhi.

How do we use asana to achieve concentration or even "single-pointed" attention? Sri K. Pattabhi Jois's Ashtanga method is incredibly powerful at helping us get there. The pratice must be understood in terms of yogaś-citta-vṛtti-nirodhaḥ -- "yoga is the cessation of the fluctuations of the mind.

Once you get that yoga is about mind, not flexibility or handstands, you appreciate a practice that values focus and one-pointedness. For me, ashtanga offers both a fiery physical practice and a deeply internal awareness (even if it is fueled by exhaustion.)

Having said all that, the class is appropriate for those new to Ashtanga, but are at least advanced beginning yoga students. Six months of Iyengar or "flow" classes would be ideal.

Sharath says 'asana is just the beginning'

I posted about Sharath's conference this week in Mysore over at Ujayii.com. Other than pushing practitioners to take on the yamas and niyamas as part of their yoga practice (asana is not the end, but the beginning), Sharath describes yoga like an ocean, which looks completely different on the surface and beneath. Check it out on Ujayii.com.

Introducing Ujayii.com

So I am experimenting with WordPress for a new blog dedicated to Ashtanga yoga, Ujayii.com. The name (with an alternative, but legit spelling) refers to the breath used in the practice. The idea is to build a site that focuses deeply on Ashtanga, taps into the Ashtanga bloggers out there and serves as a way to find Ashtanga resources wherever you are. It's very much an early experiment, so ideas and contributions are welcome.... See you there...

NY Times and Fear-Mongering

Via my Twitter pal Claudia, a new articles from the Daily Bandha: Co-activating the Gluts and Abs in Chaturanga Dandasana: Ray and Chris don't even mention the hated NY Times article on the dangers of yoga, but they slap Times writer William Broad hard:

Sociopathic corporations and individuals often resort to this form of asatya when they realize that they lack the ability to compete fairly or are afraid that someone else will gain power; they fear losing control or influence over others, mainly for monetary gain. Consequently, the fear monger acts out of fear and heads down the slippery slope of asatya. For example, they might exaggerate or fabricate scientific data to cast a false light onto something or someone they fear. Ironically, in the process, they often succeed in exposing and encouraging their own fears. An entity exposed for abusing its position of trust by deliberately misleading others will lose that position. That’s how the spiritually bankrupt become, simply, bankrupt.
That should be clear enough. Contrast this to the Kareem quote on the benefits of practice.
"I believe that yoga is one of the reasons that I was able to play as long and as healthy as I did… Yoga is somewhat hard to quantify in terms of benefits because you see them in all the injuries you don't get… For me, I noticed improvement in my posture—that was key for me because I had been having lower back problems... After I started doing yoga positions—asanas—all that changed. My health greatly improved overall."
I also like this quote from "Amy" in the Times comments:
I am appreciative that this article brings potential yoga asana injuries to our attention and reminds us that yoga is not about competition. However, I am appalled by the lack of research and comparative studies as well as the sensationalism and the misleading photos . In a former life, I worked for the flagship news show of a major network and, although, often the research did not reach the TV screen, it was always there to back it up. In a print article of this length there is the space, and certainly there must be the editorial support (NYTimes, really?), to include supporting data. I now teach nonfiction writing and I am considering using this article as an example of what not to do.

As an avid runner and Nordic skier, as well as small time farmer, I am grateful to the benefits that yoga asana practice has recently brought to my sport and work stressed body. As a mother of three teens running my own business, yoga brings calm, focus, and a positive attitude to each day I practice. My intention is to heal, not to damage, body and mind. I would be very interested in knowing how I can prevent yoga injury from a well researched, data supported, and multi-source paper.

Bringing this all back home, literally, I am visiting my dad who has been in hospital/rehab for a month. My mom asked me if yoga is dangerous, as she heard on the radio. Didn't remember any details as to how its dangerous or who said it was. But was concerned. My dad is hospitalized in large part as a result of a sedentary, meat-eating life, but yoga is dangerous... Context is ironic.

I gave her my rap: Advanced poses that your body has not been prepared for is dangerous, not listening to your body is dangerous, not having a teacher is dangerous, being competitive is stupid, not understanding it is a practice of self-awareness is risky, etc...

McYoga Sutras: Would you like a chip on your shoulder with that?


I don't know Laura Riggs, but I bet she is fun to have a drink with. Actually I am surprised she is not from L.A., but in fact she's from Denver. Anyway, she has a chip on her shoulder about corporatized yoga and a biting wit. Here are her McYoga Sutras, Chapter 1, which I am going to reprint below. But check out her bio: I wonder where she worked.
Laura started practicing yoga roughly ten years ago and began teaching five years ago. She left a successful career in advertising to teach yoga full-time because she decided it would be totally rad to pretend she was 21 again. She managed two large studios for the past two years, led many teacher trainings, and enjoyed having her soul sucked out of her. Now that the LSD in the Kool-Aid they had her drink before work each day has worn off, she is relieved to be rid of a company that believes first in money and second in “speaking your truth” — so long as it agrees with “our truth” because “our truth” can kick “your truth’s” ass! She does admit there are days that she still checks the studio’s yoga schedule and experiences flashbacks – only to be grateful she no longer has to manage the severely undereducated teachers trying their best to fulfill the studio’s mandate to “Bring the Sexy Back” to yoga. Last time she checked herself, before she wrecked herself, yoga was never sexy to begin with…..
Part 1: Self Absorption

1.1 Now begins the study and practice of McYoga

1.2 McYoga is merely for physical fitness and a means of manifesting money

1.3 The goal of McYoga is never spiritual, period, this is called self absorption

1.4 McYoga’s purpose is to teach the practitioner how to achieve self absorption and that self-identity is an illusion to be overcome.

1.5 At other times, when one is not self absorbed, the follower appears to take on the form of five modifications to conjure the mentality within the McYoga clique

1.6 These five modifications manifest as misconception, gossip, detachment, narcissism, and allegiance

1.7 Misconception is an illusionary knowledge that attending a McYoga studio will help the practitioner live an extraordinary life

1.8 Gossip is the spread of false rumors about those who are “off our path” to standardization of the physical practice

1.9 The practitioner will partake in smoking various plants from the earth to become firmly rooted in complete detachment from reality in order to enjoy attending mind-numbing raves, aka “yoga festivals”

1.10 Narcissism is achieved when the practitioner realizes detachment from others will leave one completely fixated on his/her self

1.11 Allegiance is complete when the practitioner swears loyalty to McYoga as their sole provider of all forms of physical fitness and spends their income on a monthly membership, worthless trainings, mediocre lifestyle programs, and investing in future McYoga locations

1.12 These personality modifications will be mastered through practice and aversion

1.13 McYoga makes it easy to practice 2-3 times daily now that we have 50+ locations open in the US (and another 50 slated to open this year)

1.14 Aversion is realized when one believes that they because they subscribe to McYoga, they have somehow become a better person, all the while behaving like an egomaniacal, judgmental prick

1.15 From that practice, obstacles to successful aversion begin to disappear

1.16 These obstacles are awareness, wise knowledge, empathy, humility, wise action, and honor

1.17 Accompanying these obstacles are frustration, amnesia, judgments, restlessness, disease and injury

1.18 In order to prevent these obstacles from arising, one should habituate themselves in the teaching of McYoga

1.19 By cultivating attitudes of indifference toward suffering, denial toward truth, indulgence toward vice, and anger toward others, the obstacles can be lessened

1.20 Another way to McYoga is the mastery of ignorance

1.21 Without reflection, ignorance is bliss

1.22 Without reflection, the practitioner remains in a state of ignorance to varying degrees

1.23 McYoga is born through the repression of awareness and all individuality is lost

Jane Austin at YJ conference

An old friend of North Bay Yoga (and twin to Sebastopol's No. 1 Ashtanga student/teacher Ann Austin), Jane Austin is teaching two classes at the Yoga Journal conference this weekend: Teaching Yoga to Pregnant Women and a free community class, Yoga and the True Core. Here's the true core write-up:

What is the "true core," and how do you find it? When we slow down, tune in, and listen, we have an opportunity to access this deeper place. We'll dive deep within the well of ourselves to explore our "true core"--a place that can be strong yet fluid, toned yet supple. Flowing with movement and breath, this fun and fluid practice will help connect you to your true core. Expect standing postures, core toning, and hip openers.

Lots of other awesome classes at the conference (full schedule here); of course, some people (ahem) think it's all a bit overpriced.

Getting your arms long enough for Lolasana lift

In my Intro to Ashtanga class (Sundays at 4-5:45 at the Stone Creek Zen Center - check out the schedule on yogaingraton.com), we were discussing the problem of one's arms apparently not being long enough to lift off the ground. Of course the problem isn't arm length, it's hip and ab strength. One solution of course is blocks to lengthen the arms, but as Maria Villella shows in this clip, pulling the legs into the chest provides more than enough space for the arms. ... but of course developing the strength and length to do that takes work...

A few Facebook comments on the 'dangerous yoga' article

Thanks to the amazing Kino MacGregor for posting a Facebook link to my post on the by-now infamous (and it just came out today) New York Times article, Can Yoga Wreck Your Body?, basically a hit piece on the rapid expansion of yoga, or perhaps just a call for yoga students and teachers to take the practice more seriously .

There were a few comments on Kino's Facebook post, which I repost here.

  • Philippine Yogi yoga teachers are not adequately educated in the risks and appropriate modifications.
    Friday at 6:58am · · 2
  • Lisa Cohen Phillippine...your statement is a broad generalization and not true...what IS true is that SOME teachers are not adequately educated when it comes to modifications and risks. I'm grateful for teacher training from the REAL deal...and I have learned to teach and practice from a non-ego-driven place that puts form over depth EVERY time... I also encourage my students to LISTEN to THEIR body...that their inner voice is more important than my outer one. And ANY activity has risks...especially when done from a place of ego...cyclists, runners, walkers, and most dangerous: COUCH POTATO-ers! They have the most risk of real, LONGTERM injuries...
    Friday at 7:14am · · 2
  • Chris Guzik If I were to rank what I think the culprits are that create risk for students practicing yoga, I would actually put lacking teacher competency in third place: first, I think the common led class format is problematic as it does not afford the opportunity for teachers to work one on one with students. This creates problem number two: students are not knowledgeable or aware enough to make their own determinations about modifications or backing off until it's two late. So we have led classes where students try to do what other students are doing before they are ready and injuries result - some of which do not surface until long after the class is over or as a result of repetitions over a long period of time. The Mysore method of transmission in Ashtanga addresses this issue, but that is not the norm in the average yoga studio.

  • Philippine Yogi whats good about the article is that it challenges the business of yoga and how could it be made better.

  • Jennifer Deacon We have forgotten how to walk the edge of the sword.....most people seem to fall off rather than have awareness and balance.
    Friday at 9:08am · · 1
  • Bill Leonard As practitioners we need to be reminded that 'strength' comes from ability to honor our own limitations. A majority of yoga injuries stem from ignoring the warning signs the body gives us, we must strengthen the intuition to listen within?

More crazy yoga harm

In this article, Jill Miller relates Patricia Sullivan's story in yoga journal (Sullivan was one of my teachers through Piedmont Yoga Studio) about falling asleep at the wheel as the result of nerve damages caused by headstands!
She painfully details a journey of denial in which her headstand caused (yes, caused) crippling nerve pain that eventually culminated in her falling asleep at the wheel and driving off the road into a lagoon. At last Patricia had a doctor examine her and they found “extensive damage, including a reversed cervical curve, disk degeneration, and bony deposits that were partially blocking nerve outlets.” By her own admission, “my longing to excel both in my asana practice and as an asana teacher had led me to ignore my body’s signals and cries for relief.”
Wow - attachment is powerful.

Is yoga too dangerous for a weekly class?

This Sunday, the Times will publish a radical article, How Yoga Can Wreck Your Body. It largely features New York teacher Glen Black, who is very concerned about people doing advanced yoga poses, including headstand, and creating long-term health risks.
Black has come to believe that “the vast majority of people” should give up yoga altogether. It’s simply too likely to cause harm.

Not just students but celebrated teachers too, Black said, injure themselves in droves because most have underlying physical weaknesses or problems that make serious injury all but inevitable. Instead of doing yoga, “they need to be doing a specific range of motions for articulation, for organ condition,” he said, to strengthen weak parts of the body. “Yoga is for people in good physical condition. Or it can be used therapeutically. It’s controversial to say, but it really shouldn’t be used for a general class.”

Woah! What?

Mostly the article features some pretty strange cases, like:

  • A guy who "would sit upright on his heels in a kneeling position known as vajrasana for hours a day, chanting for world peace. Soon he was experiencing difficulty walking, running and climbing stairs." Diagnosis: He deadened a branch of the sciatic nerve with all that sitting.
  • A woman was doing uhrdva danurasana prep (head balanced on the floor before pushing up) and suffered "no sensation on the right side of her body; her left arm and leg responded poorly to her commands. Her eyes kept glancing involuntarily to the left. And the left side of her face showed a contracted pupil, a drooping upper eyelid and a rising lower lid — a cluster of symptoms known as Horner’s syndrome."
  • A regular yoga practitioner suffered bruises up and down his neck and neck trauma, apparently from following Iyengar's prescription to "stretch the neck maximally against the floor."
On a more mundane level, Dr. Roger Cole, a Iyengar yoga teacher, emphasizes using blankets in shoulder stand (dangers of doing an unmodified shoulder stand: muscle strains, overstretched ligaments and cervical-disk injuries) and Timothy McCall, a physician who is the medical editor of Yoga Journal, "called the headstand too dangerous for general yoga classes" (risks: thoracic outlet syndrome, degenerative arthritis of the cervical spine, and retinal tears). Do you think the fears are overblown? Or do you think yoga teachers are not adequately educated in the risks and appropriate modifications? If you're a teacher, does this article give you pause?
