With the help of God, I have to the extent of my ability commented briefly on each of the senses and indicated the harm that they can bring to the soul when they are abused. You need all of your strength to control these senses from passionate desires and to protect yourself from any evil form that they may bring upon you. These senses after all, are, as we have noted, those very doors and windows through which either life or death may enter. Life enters when they are governed well and do not partake of their usual passions. Death enters when they partake of “corpses” as do the birds of prey; when they taste the dust of the earth as do the serpents; when they eat rotted food as do the flies. Or to put it in another way, when they partake of those sinful and death-bearing passions, which are harmful to the soul. This is why the prophet Jeremiah alluded to these senses when he said: “For death has come up into our windows, it has entered our palaces” (Jer 9:21). St. Gregory of Nyssa, interpreting this reference, explained that “the windows” through which death enters “our palace” are indeed the senses. Make every effort then to purify your soul from the impurities which the senses bring within from the outside. These senses may be likened to mountain torrents, which as soon as they swell up with the force of abundant water from the winter rains drag downhill with them everything that happens to be in their way-rocks, logs, mud, and other debris. The senses too, when allowed free reign by the controlling mind, are driven out with great force toward the physical things of life and thus draw with themselves every indecent vision, every shame*ful word, every evil sound, and generally every dirt and impurity of the passions. Afterward, when they return they bring back all these things into the troubled soul, causing it to be darkened, to be full of so many shameful images and so many conflicting sounds that, generally speaking, it is overwhelmed by the passions that make it into a den of thieves and a harbor of impurities. It was perhaps at a time when the prophet David was troubled by such torrents of the senses that he shouted to God in spiritual anguish: “The pangs of death surrounded me, and the torrents of iniquity sorely troubled me.” (Ps 17:4).
