God is the father or creator or whatever, or the source of all life, or source of our existence. Whatever you like, you can say. So we have, we have been created in that way. Eko bahu syama. God has become many. This is also version of the Vedas that many, all these many, we are also god. Just like the fire diffuses its sparks. The sparks coming out of the fire, they are also part and parcel of the fire. Similarly we, we are all parts and parcels of the Supreme. Now, He wanted to become many. He wanted to become many, so He has become many, and we are that many.
