DEUT568 The varied pleasures in life are not evil in themselves, but only when they are abused. Happiness is not only possible, it is mandatory: "And thou shalt rejoice before the Lord thy God in all that thou puttest thy hands into." [this verse] The Shechinah rests upon a man only when he is joyous, and a person will have to render an account for the pleasures that came his way, and he did not enjoy. Shabbat 30b; Yerushalmi, end of Kiddushin.
