I meditate to: a) Increase my happiness; b) Decrease my "un-happiness"; c) Directly and indirectly increase the happiness of others.
How do you practice?
I've been keeping my meditation simple for quite some time now (years) because I felt that my mind was too active and untrained to dive right into some of the more advanced meditations. But now that I feel that I can regularly calm myself during meditation, I've moved on to the Lamrim, which is 21 meditations that you cycle through (one a day). The Lamrim is a grouping and condensation of the Buddha's teachings, and it's designed to gradually take you down the path to enlightenment.
