What could be more relaxing than letting go of preferences and worries?  What can liberate our hopes and fears other than letting them arise and disassemble themselves naturally in the space of an open mind? Meditation leaves plenty of room for everything: all of our hopes, fears, and anxieties as well as our joys and aspirations. There is no need to control our thoughts, because when we practice we have committed ourselves to letting them be—not judging them as good or bad, spiritual or not spiritual, helpful or harmful. The only thing we need to practice is a quiet place to sit: a room, a park bench, or our own bed. The sutras describe a peaceful mango grove as an ideal place to practice. The Buddha and his disciples practiced meditation in such a place. If you think about it, in the midst of our busy lives, any quiet place to sit can be our modern-day mango grove.
