Yoga is not about self-development; it is about self-dissolution. It is the method or the process which allows an individual piece of life to yoke itself to the cosmic. When your experience of life shifts from being a limited entity to universality, this is yoga. When there is a kind of oneness or wholeness within ourselves, this is yoga. Then you have a certain freedom to play with your life whichever way you want, but at the same time life cannot leave a scratch upon you.
