I want to explain to you still further what I think this Prayer of Union is; and I will make a comparison as well as my wit will allow. Afterwards we will say more about this little butterfly, which never rests -- though it is always fruitful in doing good to itself and to other souls -- because it has not yet found true reposed.146 You will often have heard that God betrothes Himself to souls spiritually. Blessed be His mercy, which is pleased so to humble itself! I am only making a rough comparison, but I can find no other which will better explain what I am trying to say than the Sacrament of Matrimony. The two things work differently, for in this matter which we are treating there is nothing that is not spiritual: corporeal union is quite another thing and the spiritual joys and consolations given by the Lord are a thousand leagues removed from those experienced in marriage. It is all a union of love with love, and its operations are entirely pure, and so delicate and gentle that there is no way of describing them; but the Lord can make the soul very deeply conscious of them.
146 The words "in . . . souls" were written by St. Teresa interlineally and "because . . . repose" were added by her in the margin.
