This sublime knowledge can be received only by a person who has arrived at union with God, for it is itself that very union. It consists in a certain touch of the divinity produced in the soul, and thus it is God himself who is experienced and tasted there. This knowledge tastes of the divine essence and eternal life.
Manifestly, in this high state of union God does not communicate himself to the soul through the disguise of any image or likeness, but directly: the pure and naked essence of God with the pure and naked essence of the soul.
- St John of The Cross. Asc. 16 : 9
