Cheng Yen
Tzu Chi has a policy of being secular in its humanitarian work, however Dharma teachings are often integrated into its practices for volunteers. Cheng Yen is considered to be one of the "Four Heavenly Kings" of Taiwanese Buddhism, and Tzu Chi itself is considered to be one of the "Four Great Mountains", or four major Buddhist organizations of Taiwan along with Fo Guang Shan, Dharma Drum Mountain, and Chung Tai Shan.
