In the journey to the Divine, man has to reduce progressively his desires, which are the cause of all his difficulties. It is true that man cannot exist without desires. But they should be within reasonable limits. There can be no happiness without control of desires. Among the senses, two are most important: the eyes and the tongue. Because of their exceptional importance, the Lord has provided them with the means of restraining their activities. The Lord points out: “You silly man! Take note that I have provided natural means for closing the eyes and the mouth.” If you do not want to see anything undesirable, you can close your eyes with the eyelids. The ears and the nose have no such devices for closing them. The mouth has lips which can seal the tongue. Observe, therefore, restraint in speech and control the tongue. When the eyes roam freely, the tongue begins to wag without restraint. When the tongue is engaged in endless talking, the eyes want to look at every conceivable thing. When both these organs combine without restraint, life can become a calamity. Therefore, direct your eyes to good things alone.
