 St. St. Basil the Great says: "The exercise in virtue is likened to the ladder that the blessed James once saw, with which one part was close to the earth and touched it, and the other stretched above heaven itself" (St. Basil the Great, Creations, Ed. 3. Part 1. Moscow, 1891. P. 155). "The Ladder" of St. St. John clearly carries out this idea of the interdependence of both virtues and passions in the spiritual life of a Christian.

 St. Isaac of Syria says: "Every virtue is the mother of another virtue. Therefore, if you leave the mother who gives birth to virtues, and go to look for daughters before you find their mother, then these virtues turn out to be vipers for the soul. If you do not reject them, you will soon die" (St. Isaac of Syria, Words of Asceticism, Moscow, 1858, Word 72, p. 528).
