How can one unlearn? You would say that the character of the mind is such that what one learns is engraved upon it, and how then can one unlearn it? Unlearning is completing knowledge. To see a person and say: "That person is wicked" - that is learning. To see further, and recognize something good in that person - that is unlearning. When you see the goodness in someone whom you have called wicked, you have unlearned. You have unravelled that knot. You have once said: "I hate that person'- that is learning. And then you say: "Oh no, I can like him, or I can pity him." When you say that, you have seen with two eyes. First you learn by seeing with one eye; then you learn to see with two eyes. That makes sight complete.
