無目的之樂 Happiness without a Purpose

生命於不知目的前，可享無目的之樂，不可享有目的之樂。	Before we understand the meaning of "purpose", we can enjoy the happiness without a purpose, but cannot enjoy happiness with a purpose.
生命於知目的後，可享有目的之樂，難以享無目的之樂。蓋目的自無至有易，自有至無難。	After we understand the meaning of "purpose", we can enjoy happiness with a purpose, but hardly enjoy happiness without a purpose, because it is easy to seek a purpose but hard to leave a purpose.
