of course, this isn't really discussed much in the American yoga tradition, which treats asana (and to a lesser extent pranayama, the breathing practice) as the entirety of it
but the lessons are there for those who seek them out
I was one such, autistically obsessing over it
yoga became a major part of my life, both with the physical/social practice in yoga studios, and a more personal practice of pranayama and meditation
this, with no exaggeration, changed my life, and showed me a new way to relate to my physical, emotional, & spiritual selves
