So far, the emergent theme of yoga school is this: you're perfect.
The training is an integrated approach to Hatha yoga (physical practice, asanas), comprising elements of Ashtanga, Anusara, Bikram, Kundalini, etc. It's broad, it's open, it's inclusive, it's accepting.
That's not to say it's a free-for-all where anything goes. For example, there are safe ways and horrifying ways to move into upward facing dog (urdhva mukha svanasana), and if you take a horrifying option (crane your neck up to the ceiling, sinking into your shoulders and compressing your lower spine), you'll probably get hurt.
But to offer alternatives without authenticity is pointless...it will get everyone nowhere. It's important, I think, to illustrate, teach, and speak with equal parts compassion and knowledge--to recognize why people might be wrenching down into a heart-opener rather than letting their solar plexus move forward--maybe there's darkness there, maybe they're not ready to deal with what they've been hiding in that space. Lots of poses--even breathing exercises--take courage. You can't force courage--it has to be nurtured.
But this isn't news.
Plenty of wiser people than I have been talking about this stuff for years. Here are two exmples:
An organic structure is aligned with who we are and what we have to say. It is not disconnected from ourselves. If a form isn't organic, I think a great struggle ensues--the writer tries to stuff her being into a costume that doesn't fit.
Men ask the way to Cold Mountain
Cold Mountain: there's no through trail.
In summer, ice doesn't melt
The rising sun blurs in swirling fog.
How did I make it?
My heart's not the same as yours.
If your heart was like mine,
You'd get it and be right here.
