The whole universe is a manifestation and product of that universal, formless. causeless Being. The sun, moon and all quarters, all knowledge, and the souls of all existing beings are parts and manifestations of that single all-immanent Being. All life and all qualities, functions and activities are forms of that single Energy. He is Fire which has lighted the sun and makes it burn, like a log burning in fire. Thereby does the sun give us warmth and light. The rain does not rain, but it is He that rains through clouds. Beings come together and multiply, but it is He above that multiplies through them.
