“According to Yoga, Prana is the energy or vital fluid. The universal conciousness that give life to matter.
(…) We find it in the air, in fresh food and in the sun light, but the main process of intake of Prana is breathing.
(…) Yoga says the universe is made of akasa and prana, which would stand for matter and energy. All forms come from the action of prana upon akasa.”
