He is transcendent, and beyond such limited understanding. With uncounted heads Uncounted eyes, and Uncounted feet, He Moves, as all of Creation Verily is He Uncountable. Beyond the grasp Of the hands of men. Purusha is creation, this we know. In time, he is all that is, all that was, and all that is to be.
Creation feeds on itself.
It requires food to grow, to flourish. Life feeds on life, be it plant, or animal life. All that is hidden in creation, and all that emerges, to show itself and be food, all this is purusha. He sustains creation as food. That which is, Was, and is to be.
