I'm reading "Autobiography of a Yogi" - by Parmahansa Yogananda. I've glanced at it in the past but never truly read it cover to cover. I'm almost finished.
First published in 1946, it tells the story of a man who dedicated his life to getting close to his personal understanding of God through the science and practice of yoga (specificially "Kriya Yoga").
The story speaks to me in many ways and on many levels. Yoganada's dedication, diligent practice, human-ness, and vulnerabilities all come through the pages.
The practice of yoga can change anyone's life for the better - I am totally convinced - no further proof is required.
I envision the day when we all look back on our life as yogis.
