Supreme Lord is One. He cannot be more than one. He is Infinite and Absolute. If we think anything can be outside Absolute, Absolute will lose His position. So, onto-logically God is One. But He has got Infinite Manifestations. His everything is infinite – Infinite creations, infinite created worlds, infinite transcendental realms etc. As per degree of the submission of the aspirant,Lord’s transcendental qualities will descend to him. But that is not the end. Nobody can finish realization of Supreme Lord. It will go on ad infinitum.
