Buddhism in general, and certainly Tibetan Buddhism, places great importance on happiness. The emphasis in Mahayana Buddhism, though, is not on one’s own happiness, but rather that of all sentient beings. When we strive for the welfare of all beings, at the same time we attain even greater happiness for ourselves. This well-being ultimately surpasses any that material enjoyments can bring. Such is the Tibetan Buddhist view of happiness.
