If a person thinks, "Everything I touch and everything I do and everywhere I look, it is all wrong", certainly it is wrong, there is no doubt about it; but it is his attitude that is wrong, and therefore whatever he does is wrong. It is just like taking a red lantern and throwing its light upon everything: every object in that light will appear red, and one will become frightened oneself and see danger everywhere. But the danger is in one's own hand; it is the red lantern.
