Before every one of them was made, they all existed potentially in the clay, and, of course, they are identical substantially; but when formed, and so long as the form remains, they are separate and different; the clay-mouse can never become a clay-elephant, because, as manifestations, form alone makes them what they are, though as unformed clay they are all one. Ishvara is the highest manifestation of the Absolute Reality, or in other words, the highest possible reading of the Absolute by the human mind. Creation is eternal, and so also is Ishvara.
