If the individual merges into pure Being, what is the ego which ceases to exist? For the physical body still remains and must be included in a man's consideration. This is one reason why even the highest mystical attainment must be naturalized, integrated even with his normal life as householder, professional, or intellectual. He then functions on three levels--animal, human, and angelic--but they fit together in harmony like a mosaic tiled wall. Whoever thinks otherwise is confusing two different situations, is superimposing the seeker upon the fulfilled man. If, for instance, he grants the possibility to monks alone, then he puts a limit on the Limitless and narrows the area of its presence. For the man who is established in the Light will act from within and by it, no matter whether he be engaged in the world's work, no matter whether married or not.
