Ashtanga Yoga: The Breath of Life http://yoga-gurus.blogspot.com/2008/09/ashtanga... In many languages the words for spirit and breath are the same. In Sanskrit it’s prana, in Latin, spiritus, and in Hebrew, ruach. In Portuguese the word for taking in breath is inspiration, or spirit-in. They believe that an infant literally breathes its spirit into its body with its first breath. We breathe in life. Breath is the source of life and vitality. It is the spirit moving in rhythm in the body. When the breath wanders, the mind is unsteady, but when the breath is still, so is the mind still.
