Our Earth and Water element of body accepts the physical food, our fire element digests the food which create energy and chemicals for functioning
of body and brain, air element(the mental body) digests that physical energy and create impression and memory and alters the thought and cognitive
process, space element(the chitta) digests all that impression and creates a state which alters our consciousness.
Food is not only what we eat and digest, food reaches to multiple layers, it creates a sequence of event from form to consciousness.
I Love Food :)
