God exists as form and as non-form. Just as the light is not recognizable other than in something on which it shines, there is no God for us without form. If there is nothing that the light shines on, you don’t see the light either. We could even say that what we refer to as an illuminated object is nothing more than bundled light! ...This is precisely the case with God. There exists only God, because God’s very self is being. Everything that exists is an appearance of being, "bundled being" so to speak. This is what the mystic experiences.
