Self is One without a second.

Yes, Self is One without a second. Oneself itself is and separation there is none. All there is is Oneself experiencing itself as manifoldness for the purpose of its own enjoyment, for the purpose of companionship, for the purpose of love. All that is is Oneself and Oneself is all that is. There is no supreme or lesser Self; all there is is Oneself. Oneself itself is. ~ Wald Wassermann
