“In the orison of union,” says Saint Teresa, “the soul is fully awake as regards God, but wholly asleep as regards things of this world and in respect of herself. During the short time the union lasts, she is as it were deprived of every feeling, and even if she would, she could not think of any single thing. Thus she needs to employ no artifice in order to arrest the use of her understanding: it remains so stricken with inactivity that she neither knows what she loves, nor in what manner she loves, nor what she wills. In short, she is utterly dead to the things of the world and lives solely in God.... I do not even know whether in this state she has enough life left to breathe. It seems to me she has not; or at least that if she does breathe, she is unaware of it. Her intellect would fain understand something of what is going on within her, but it has so little force now that it can act in no way whatsoever. So a person who falls into a deep faint appears as if dead.... “Thus does God, when he raises a soul to union with himself, suspend the natural action of all her faculties. She neither sees, hears, nor understands, so long as she is united with God. But this time is always short, and it seems even shorter than it is. God establishes himself in the interior of this soul in such a way, that when she returns to herself, it is wholly impossible for her to doubt that she has been in God, and God in her. This truth remains so strongly impressed on her that, even though many years should pass without the condition returning, she can neither forget the favor she received, nor doubt of its reality. If you, nevertheless, ask how it is possible that the soul can see and understand that she has been in God, since during the union she has neither sight nor understanding, I reply that she does not see it then, but that she sees it clearly later, after she has returned to herself, not by any vision, but by a certitude which abides with her and which God alone can give her. I knew a person who was ignorant of the truth that God’s mode of being in everything must be either by presence, by power, or by essence, but who, after having received the grace of which I am speaking, believed this truth in the most unshakable manner. So much so that, having consulted a half‐learned man who was as ignorant on this point as she had been before she was enlightened, when he replied that God is in us only by ‘grace,’ she disbelieved his reply, so sure she was of the true answer; and when she came to ask wiser doctors, they confirmed her in her belief, which much consoled her....
