another of the Buddha's teachings:
"There are two kinds of happiness. There is that of an uncommitted life of sensual pleasures, and there is that of a committed life, one of going forth to a new consciousness. Of these, the happiness of going forth is the greater." ~ Buddha, the Tathagata
This does not mean one must ordain to be happy though 'going forth' is often used to mean ordination. Going Forth is to take the step to be alive, to live consciously, not without desire but with desire for happiness and joy for all, with clarity and the happiness of kindness. If repeatedly throughout the day one stops and reflects: "ah, this is life, life is short by nature, what is wondrous and joyful right now?" and makes this a habit, then one is gone forth.
