The blemish that affects the mind is illusion. It is like a fierce dog that will not allow anyone to approach the Master. You can manage to bypass it only by assuming the rupam or form of the Master, which is called sarupyam, or by calling out for the Master so loudly that He comes down and accompanies you into the house, that is to say, by winning His Grace, samipya (proximity). Illusion is His pet, and so, it will not harm you if He orders it to desist from harming you. The Master comes to save not one good man from illusion, but the whole of mankind. Of course, He has to come assuming a form that man can love, revere, and appreciate. He can give joy and courage, only if He speaks the language of human conversation. Many are afraid to approach Me, for they know I am aware of their innermost thoughts and deepest desires. But let Me tell you, only helpless animals have fear. Man, who is the child of immortality, should have no fear. People pray before stone images of the snake god, but when the actual snake appears in answer to their prayers, they run away, terror-stricken from the shrine! The Lord manifests Himself only to shower Grace, never to strike terror. – Divine Discourse, Jan 01, 1964
