The one Brahman, through His Sakti, can put on all these countless names and forms and appear as many. There is no change in Himself. The world is mere appearance. Brahman does not require any instruments or hands for making these forms. He is Chaitanya, self-luminous intelligence. By mere willing, He can bring forth countless worlds. Just as the potentiality of a seed brings forth a tree, so also, the Svabhava or potentiality of Brahman brings forth this universe. Projection coexists with existence.
