The Dalai Lama will tell you how, in a live webcast later today:
I have a great deal of respect for the Dalai Lama, but I find that the Tibetan tradition - which was may gateway drug to the dharma, many years ago - puts too much emphasis on "happiness," and not enough of relieving suffering, and contentment. Perhaps, back in the day, I would have considered that sitting and the dharma were about finding happiness, but I know now that's not the case. Yet the Tibetans keep peddling the same old spiel...
Contentment is, today, drinking a nice cup of tea, listening to Leonard Bernstein conducting Charles Ives, playing with my cat, talking with my girlfriend, and being sheltered from the winds outside. I've learned to be satisfied with simple things.
