Ultimately, we're not here for anything. We are part of the process of reality doing it's thing, and reality cannot possibly be for anything other than itself. That said, since we are here, and we have to make choices about what we are going to do, there are some general guidelines in how to apply ourselves. These are things that will lead to greater long-term happiness for yourself and those you care about, which is really what we want. First, overcome the illusion of separation. Recognize yourself as an embodiment of the great spirit that is already whole and complete. Deeply internalize that recognition and let it transform your relationship to your life. Second, cultivate positive emotional states in yourself and seek to share these with others. Third, increase your personal power, not for its own sake but so that you can more effectively make the sphere around you flourish with life, love, and kindness.
