One is for One is: Creatio Ex Amore Sui.

Existence is One, — existence exists for God exists as (the allness or totality) of existence itself; All is Oneself. One is for One is Self Love itself. I will, therefore, call this One 'Creatio Ex Amore Sui'; naturally, you can also name this One Love or God for all is one and the same.
