We learn from the Taittiriya upanishad: “Out of Brahman, who is the Self, came ether; out of ether, air; out of air, fire; out of fire, water; out of water, earth; out of earth, vegetation; out of vegetation, food; out of food, the body of man. The body of man, composed of the essence of food, is the physical sheath of the Self.
From food are born all creatures, which live upon food and after death return to food. Food is the chief of all things. It is therefore said to be medicine for all diseases of the body…From food are born all beings which, being born, grow by food. All beings feed upon food, and, when they die, food feeds upon them.”
There! We have come full circle…Food is medicine!
