Continuing on his spiritual path, the Fool begins to wonder how to reconcile the opposites that he's been facing: material and spiritual , death and birth.
It is at this point that he comes upon 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!

"How can you mix fire and water?" the Fool finally whispers.
Never pausing the Angel answers, "You must have the right vessels and 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 to harmonize. It is only a lack of will, a disbelief in the possibility of unity, 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. In him, the two could merge, as in the vessels that the Angel uses to pour the elements, one to the other. All it takes, the Fool realizes, is the right proportions....and the right vessel.
