The eyes do not become more powerful by looking in the mirror. Only, the eyes know what they are like when they see their reflection. The pleasure is in realizing one's merits, one's gifts, what one possesses. It is in realizing that the merit lies. No doubt it would be a great pity if the eyes thought: "We are as dead as this mirror", or if in looking in the mirror they thought: "We do not exist except in the mirror." So the false self is the greatest limitation.
