God is infinite in His simplicity and simple in His infinity. Therefore He is everywhere and is everywhere complete. He is everywhere on account of His infinity, and is everywhere complete on account of His simplicity. Only God flows into all things, their very essences. Nothing else flows into something else. God is in the innermost part of each and every thing, only in its innermost part, and He alone is One.... All things are contained in the One, by virtue of the fact that it is one, for all multiplicity is one, and is one thing, and is in and through the One…. God unites things with Himself only because He is one and only in so far as He is one. Indeed, He must unite all things, uniting them with and in Himself on the grounds that He is Himself One.... The One is not distinct from all things. Therefore all things and the fullness of being are in the One by virtue of its indistinction and unity.... The One descends into everything and into each single things, yet remaining the One that unites what is distinct. That is why six is not twice three but six times one.... God, the One, is.... He is the Being of all beings.
~Meister Eckhart
