The fool at this point comes up before a winged figure standing with one foot in a brook, the other on a rock. The radiant creature pours something from one flask into another. Drawing closer, the Fool sees that what is being poured from one flask is fire, while water flows from the other. The two are being blended together into a completely different substance!
"How can you mix fire and water?" the Fool finally whispers. Never pausing the Angel answers, "You must have the right vessels and use the right proportions."
The Fool watches with wonder. "Can this be done with all opposites?" he asks. "Indeed," the Angel replies, "Any oppositions, fire and water, man and woman, thesis and anti-thesis, can be made into a unified third. It is only a lack of will and a disbelief in the possibility that keeps opposites, opposite." And that is when the Fool begins to understand that he is the one who is keeping his universe in twain, holding life/death, material world and spiritual world separate. In him the two could merge. All it takes, the Fool realizes, is the right proportions, the right vessel and enough faith that the two can be unified.
