"The 'opening' (fath) is the sudden revealing of Divine Reality and thus the end of the illusion. It's like a ball of snow which one throws in the ocean. The ball of snow is the ego (nafs) and the ocean is the Divine Reality. The ball of snow is nothing but frozen water. Once thrown in the ocean, it becomes again liquid. Ego has only a transitory and illusory existence if one considers it in itself, cut of its origin. In the same way as the ball of snow, if one relies on its present state, with its actual consistency, it seems different from water; it appears to be of an original nature. Actually, it is nothing but water, a drop similar to all the other drops of the ocean. There is only one water and various states of this same water."
