Sangha is one of the three treasures (Buddha, Dharma, and Sangha) in which we take refuge. Practicing in a supportive community is essential to the development of the wisdom and compassion that leads to transformation.
Serving the sangha is both a way to engage in the practice and a way to ensure that this important container is available for others. If you feel serving the sangha in some way would enhance your practice, you may want to investigate the variety of volunteer opportunities available at Dharma Rain. See Ways to Volunteer.
