Imagine Brahman as a sea without shores. Through the cooling love of the bhakta some of the water becomes frozen into blocks of ice. Now and then, God assumes a form and reveals Himself to his lovers as a Person. But when the sun of Knowledge rises, the blocks of ice melt away and God is without form, no more a Person. He is beyond description. Who could describe Him? Anyone who tries disappears, unable to find his "I" any more.
