The guru destroys the illusion and sheds light; his presence is cool and comforting. That is why this day, a full-moon day, is allotted for paying due honour to the guru. Moreover, the moon is the presiding deity of the mind, and the full-moon day is the day on which the mind has become fully beneficent. Of course, you must know what you have lost, so that you may start on the search to recover it! The guru has very often to tell you that you have forgotten your real name or that you have lost the most precious part of yourself and yet are unaware of the loss. The guru is the physician for the illness that brings about the suffering of alternate birth and death. He is an adept at the treatment needed for the cure. If you do not get such a guru, pray to the Lord Himself to show you the way and He will surely come to your rescue.
