Buddhism teaches us that happiness does not come from any kind of acquisitiveness, be it material or psychological. Happiness comes from letting go. In Buddhism, the impenetrable, separate, and individuated self is more of the problem than the solution.

When we seek happiness through accumulation, either outside of ourselves--from other people, relationships, or material goods--or from our own self-development, we are missing the essential point. In either case we are trying to find completion. But according to Buddhism, such a strategy is doomed. Completion comes not from adding another piece to ourselves but from surrendering our ideas of perfection.

If aspects of the person remain undigested--cut off, denied, projected, rejected, indulged, or otherwise unassimilated--they become the points around which the core forces of greed, hatred and delusion attach themselves.
When we immerse ourself in desire without guilt, shame or clinging, it can show us something special about our own minds that allows us to embrace life fully.
