Most of those who claim to know God make the knowledge of God dependent the passing away of existence and on the passing away of the passing away. That is clearly an error and misconception. The knowledge of God does not require the passing away of existence or the passing away of that passing away because things have no existence and what does not exist cannot pass away. Passing away implies the prior existence of the thing that passes away. If you know yourself without existing and passing, then you know God, and if not, then not.
