3.3 Listen

Translation by Swami Sivananda
3 This prana is born of Atman. As a shadow is cast by a person, so this prana is, by Atman. Through the activity of the mind it comes into this body. 

Translation by Max Mueller
3. This Prâna (spirit) is born of the Self. Like the shadow thrown on a man, this (the prâna) is spread out over it (the Brahman). By the work of the mind does it come into this body.
