Ein Sof was all that existed. Similarly, after it brought into being that which exists, there is nothing but it. You cannot find anything that exists apart from it. There is nothing that is not pervaded by the power of divinity. If there were, Ein Sof would be limited, subject to duality, God forbid! Rather, God is everything that exists, though everything that exists is not God. It is present in everything, and everything comes into being from it. Nothing is devoid of its divinity. Everything is within it, it is within everything and outside of everything. There is nothing but it.
When you contemplate the Creator, realize that His encampment
extends beyond, infinitely beyond, and so, too, in front of
you, and behind you, east and west, north and south, above
and below, infinitely everywhere. Be aware that God fashioned
everything and is within everything. There is nothing else.
