A good presentation touching upon mystical theology. Added to that, what better resource is there than the words of a Catholic Doctor and mystic?

Wherefore any soul that makes account of all its knowledge and ability in order to come to union with the wisdom of God is supremely ignorant in the eyes of God and will remain far removed from that wisdom; for ignorance knows not what wisdom is, even as Saint Paul says that this wisdom seems foolishness to God; since, in the eyes of God, those who consider themselves to be persons with a certain amount of knowledge are very ignorant, so that the Apostle, writing to the Romans, says of them: Dicentes enim se esse sapientes, stulti facti sunt. That is: Professing themselves to be wise, they became foolish.Romans i, 22.

And those alone acquire wisdom of God who are like ignorant children, and, laying aside their knowledge, walk in His service with love. This manner of wisdom Saint Paul taught likewise ad Corinthios: Si quis videtur inter vos sapiens esse in hoc soeculo, stultus fiat ut sit sapiens. Sapientia enim hujus mundi stultitia est apud Deum. Corinthians iii, 18-19. That is: If any man among you seem to be wise, let him become ignorant that he may be wise; for the wisdom of this world is foolishness with God. So that, in order to come to union with the wisdom of God, the soul has to proceed rather by unknowing than by knowing; and all the dominion and liberty of the world, compared with the liberty and dominion of the Spirit of God, is the most abject[Lit., ‘is supreme.’] slavery, affliction and captivity. St. John of the Cross.

In summary:
But, as it is written: That eye hath not seen, nor ear heard, neither hath it entered into the heart of man, what things God hath prepared for them that love him. I Cor 2:9
