Then, the Vedas would have asked us to worship only one form but with various names. whereas, each god has a different form, name, functionality [like the various cosmic entities have different purpose]. Shouldn't then mean that the various gods are individuals with different powers, and all of them originated with the powers/will of Brahman? Then why would the upanishad say, 'Sat (That Pure Being) alone existed in the beginning'. If all are the forms of the same Brahman, then why would the creation from Brahma to Shiva to manus to prajapatis to other living beings, be hierarchical?
