Only an Iyengar student knows how amazing this type of work is. Yoga is not a lazy dull practice, never was or ever should be. Yoga should be about a very intimate relationship with yourself. I witness regularly students reconnecting back to themselves after decades of not be physically or mentally conscious.
People are running off to all kinds of therapies but everything can be found on your mat. Look for yoga teachers who can give you honest guidance. Try to avoid crowd pleases and find yourself with someone who will make you question who and what you really are.
