Preserve a loving attentiveness to God with no desire to feel or understand any particular thing concerning God. - John of the Cross

Therefore, if we would listen to the voice of God15 with due reverence, the soul must stand upright, and not lean on the affections of sense for support. As the prophet Habakkuk says of himself, “I will stand upon my watch, and fix my step upon the munition, and I will behold to see what may be said to me.”16 To stand upon the watch is to cast off all desires; to fix the step, is to cease from reflections of sense, that I may behold and understand what God will speak to me. Thus out of this night springs first the knowledge of one’s self, and on that, as on a foundation, is built up the knowledge of God. “Let me know myself,” says St. Augustine, “and I shall then know Thee, O my God,” for, as the philosophers say, one extreme is known by another.

When the soul has arrived at this state all the acts of its spiritual and sensual nature, whether active or passive, and of whatever kind they may be, always occasion an increase of love and delight in God: even the act of prayer and communion with God, which was once carried on by reflections and divers other methods, is now wholly an act of love. So much so is this the case that the soul may always say, whether occupied with temporal or spiritual things, "My sole occupation is love." Happy life! happy state! and happy the soul which has attained to it!

The soul is purified also in this aridity of the desires from the imperfections of the other three capital sins of which I have spoken,7 envy, anger, and sloth, and acquires the opposite virtues. Softened and humbled by these aridities, by the hardships, temptations, and afflictions which in this night try it, it becomes gentle with God, with itself, and with its neighbor. It is no longer impatiently angry with itself because of its own faults, nor with its neighbor because of his; neither is it discontented or given to unseemly complaints against God because He does not sanctify it at once. As to envy, the soul is in charity with every one, and if any envy remain, it is no longer vicious as before, when the soul was afflicted when it saw others preferred to it, and raised higher; for now it yields to every one considering its own misery, and the envy it feels, if it feels any, is a virtuous envy, a desire to emulate them, which is great virtue.
