In fact we ourselves, limited as we are, have mercy in us, so that often if someone has done something against us we would forgive. If he only bows before us we say, "He has humiliated himself, I will forget." Even if a son has caused his mother much sorrow, when he is in trouble, he only needs to say, "Mother, I have done this, but you are the one to whom I can come for sympathy", and she will say, "My child, I forgive you, though at the time it made me sad."
