True knowledge of anything means as deep a union with your subject as that experienced in sexual intercourse. The knower, the known and the act of knowledge become one. You forget that you and your partner exist. You no longer think, but your mind is dissolved in the heat of the embrace.
It is perhaps in this sense that Meister Eckhart, the great German mystic, said that the Christian, in abandoning all things, must also abandon God. As long as you are still conscious of having a God, you have not yet become one with him.
The man who thinks and reasons about truth, shows by this that he does not possess it. Whoever has met King Truth, and has known his ardent kiss, does not seek the truth any longer, does not speak the truth, but is its very embodiment. Christ is no longer the object of your thoughts. You are his manifestation. Instead of being like Christ, you are identified with him. He is the light of the world. You are the light of the world. You are the same light.
