One should not approach the ascetic life with the express hope or goal of divine visions, for fear that Satan finds the soul susceptible to deceit from then on. The goal is to arrive at the love of God in a feelings of total certainty of the heart, which means all of one's heart, all of one's soul, all of one's thoughts (cf. Luke 10:27). The one who is moved through the grace of God lives far from the world, even when he is present in the world.
