The Taittiriya tells us, there was thus the creation down to the earth, and from the earth arise vegetations of various kinds, herbs or Aushadhis which become the diet of the individual, the Purusha, Aashadhibhyah Annam, Annat Purushah , the individual grows out of the food that he takes. Here is again an interesting factor that we have to observe. We are constituted of Anna or food. It is not merely the physical body that is constituted out of food but everything that we are is nothing but the food that we take. As cloth is made of threads, as any composite object is made up of the component factors, so is the total individuality of ours, including the psychic individuality, constituted of certain bits of experience and bits of matter.
Thought is nothing but the various functions it performs.
The various feelings and emotions and the volitions put together constitute what we call the mind, the fabric of psychic personality. The body again is constituted of these elements only, - earth, water, fire air and ether, etc. Everything in the so-called individuality of ours is a composite structure or Sanghatta of various factors which can be dismembered and broken into their component parts. These compositions of individuality become the causes of the various experiences we pass through in our life. Our experiences are through the layers of our personality.
