The Compassionate Service Society is a non-profit 501(c)3 organization based in Southern California, USA. Venerable Hang Truong founded CSS in 2000.


Though founded on Buddhist principles, CSS takes an ecumenical and all-inclusive approach that transcends religious and cultural boundaries. By integrating the ancient teachings of Buddhism with the best of 21st-century thoughts, practices, philosophies, and knowledge, CSS seeks to bring unity and healing to the body, mind, and spirit.


Our goal is to facilitate the practice of Bodhisattva’s ideals (altruism) and promote holistic living.


In Buddhism, a Bodhisattva is someone who has a generous heart, mature character, and profound wisdom imbued with kindness and compassion, and who dedicates energy and service to the betterment of other beings.


To effectuate our goal, CSS creates a learning center (both physical and online). The Center provides a nurturing environment for those who seek to practice holistic living and incorporate altruism into their lives.


The integral model for holistic living is to develop all four dimensions of our life (spiritual, emotional, intellectual, and behavioral) within the four living/life conditions (physical/body, nature, culture, and social system).


“Our mission is to create a spiritual and healing environment for body, mind, and spirit.”


The purpose of the Center (physical Center in Orange County, California) is to develop, foster, and promote spiritual growth, emotional harmony, and physical wellness as experiences central to the lives of our Buddhist communities.


Toward this end, we provide holistic training in body, mind, and spirit. The Center will undertake the following activities:

  • Integrate mind, body, and spirit.

  • Provide training to develop spiritual awareness.

  • Promote health and well-being.

  • Encourage creativity.

  • Promote emotional and social harmony.
