Creation Of Brahmand And Brahma.

That implanted seed took the form of a bright egg that enlightened with a luster of thousands of Suns. After that Brahma born out from the same egg who been the creator of all the worlds. Manu Smiriti 1/11
Thus the whole universe developed by the seed that God Parmatma implanted into nature. Therefore it is evident that God Parmatma were present before the creation, is present in the middle or at present and will be present on the end of the creation. The Brahma has born from the same God Parmatma. He merely is the cause, doer and deed as well.
