It is natural. One should not feel discouraged because one has made a mistake; one should not feel discouraged that one did wrong. One should only think, "There is the whole life for us to learn. If today we do wrong, tomorrow it will be better." There will always be a hope. One must never think, "No, no, I don't know how to do the work. I shall always be doing wrong." Never think about it. Life is a school where one learns a lesson; every day we do wrong, and every day we improve if we care to learn from it. If we only study, we can go forward by doing wrong. But if we lose our hope and enthusiasm and say, "I made a mistake yesterday; I am not fit for the work," that is not right.
