Marvelous how His Real Presence gives us what we need, when we are needful and ready to receive.
From the works of Pseudo-Dionysius, The Mystical Theology....
"...my advice to you as you look for a sight to the mysterious things, is to leave behind you everything perceived and understood, everything perceptible and understandable, all that is not and all that is, and with your understanding laid aside, to strive upward as much as you can toward union with him who is beyond all being and knowledge.
"By an undivided and absolute abandonment of yourself and everything, shedding all and freed from all, you will be uplifted to the ray of the divine shadow which is above everything that is."
And then this bit of advice is so apropos, as well!
"But see to it that none of this comes to the hearing of the uniformed, that is to say to those caught up with the things of the world, who imagine that there is nothing beyond instances of individual being and who think that by their own intellectual resources they can have a direct knowledge of him who has made the shadows his hiding place.
"And if initiation to the divine is beyond such people, what is to be said of those others, still more uniformed, who describe the transcendent Cause of all things in terms derived from the lowest orders of being, and who claim that it is in no way superior to the godless, multiformed shapes they have made? What has actually to be said about the Cause of everything is this.
"Since it is the Cause of all beings, we should posit and ascribe to it all the affirmations we make in regard to beings, and more appropriately, we should negate all these affirmations, since it surpasses all being. Now we should not conclude that the negations are simply the opposites of the affirmations, but rather that the cause of all is considerably prior to this, beyond privations, beyond every denial, beyond every assurance."
There is more, not much more, but perhaps for another time. He shares more of God and our ascension into Him, our assumption, our subsummation--perhaps this is the way to describe, without being able to ever describe our union with God.
