There is a third thing we should understand concerning this subject which is of great importance: that which stands between vacuum and substance is capacity. When we look at the sky we feel that it is a vacuum; it seems to be nothing, but in reality it is not nothing, it is capacity. Vacuum is all-knowing, but it is capacity which enables vacuum to know. And as the sky is a capacity for the vacuum to be all-knowing, so every being and every thing is a capacity, greater or lesser, which supplies a body or a vehicle for pure intelligence to work through. There is nothing in this world, whether a stone, a tree, a mountain or a river, water or fire, earth, air, anything, which is not in itself a capacity; it cannot exist without being a capacity. Therefore all that exists, whether living or not living, is a capacity. We read in the scriptures that every atom moves by the command of God. In other words, behind everything that exists, be it large or small, in every motion it makes, even the slightest, there is the hand of the Spirit. It cannot act or move otherwise.
