Sometimes in prayer…

Sometimes, in prayer, God communicates to the soul, all at once, His treasures of lights and heavenly graces. Imagine that you have in your hand a golden dish, that you pour into it the extract of the rarest and most exquisite perfumes, and that you steep into it a fine cambric handkerchief; this handkerchief will yield a delicious and inexplicable odor, composed of all the perfumes. It is thus my soul feels when I receive those intimate and hidden communications.
–Saint Paul of the Cross (1694-1775)

The contemplation of God…

Furthermore, while the soul is withdrawn from everything and is turned within, the eye of contemplation is opened and sets itself up a ladder by which it can pass to the contemplation of God. By this contemplation the soul is set on fire for eternal things by the heavenly and divine good things it experiences, and views all the things of time from a distance and as if they were nothing. Hence when we approach God by the way of negation, we first deny him everything that can be experienced by the body, the senses and the imagination, secondly even things experienceable by the intellect, and finally even being itself in so far as it is found in created things. This, so far as the nature of the way is concerned, is the best means of union with God, according to Dionysius.
–Saint Albert the Great (c. 1206-1280)
