"Do you know how these three virtues stand together? It is, as if a circle were drawn on the surface of the earth, and a tree, with an off-shoot joined to its side, grew in the center of the circle. The tree is nourished in the earth contained in the diameter of the circle, for if the tree were out of the earth it would die, and give no fruit. Now, consider, in the same way, that the soul is a tree existing by love, and that it can live by nothing else than love; and, that if this soul have not in very truth the divine love of perfect charity, she cannot produce fruit of life, but only of death. It is necessary then, that the root of this tree, that is the affection of the soul, should grow in, and issue from the circle of true self-knowledge which is contained in Me, who have neither beginning nor end, like the circumference of the circle, for, turn as you will within a circle, inasmuch as the circumference has neither end nor beginning, you always remain within it.

"This knowledge of yourself and of Me is found in the earth of true humility, which is as wide as the diameter of the circle, that is as the knowledge of self and of Me (for, otherwise, the circle would not be without end and beginning, but would have its beginning in knowledge of self, and its end in confusion, if this knowledge were not contained in Me). Then the tree of love feeds itself on humility, bringing forth from its side the off-shoot of true discretion, in the way that I have already told you, from the heart of the tree, that is the affection of love which is in the soul, and the patience, which proves that I am in the soul and the soul in Me. This tree then, so sweetly planted, produces fragrant blossoms of virtue, with many scents of great variety, inasmuch as the soul renders fruit of grace and of utility to her neighbor, according to the zeal of those who come to receive fruit from My servants; and to Me she renders the sweet odor of glory and praise to My Name, and so fulfills the object of her creation.

"In this way, therefore, she reaches the term of her being, that is Myself, her God, who am Eternal Life. And these fruits cannot be taken from her without her will, inasmuch as they are all flavored with discretion, because they are all united, as has been said above."
