In the Chinese Chan (Zen) tradition, silent illumination refers to the natural awakened mind. It is also a method of cultivation, the simultaneous practice of stillness and clear-seeing, quiescence and luminosity, or samādhi and prajñā. It is similar to the practices of śamatha and vipaśyanā (Pāli: vipassanā) in the Theravada tradition and the shikantaza (“just sitting”) practice of Japanese Soto Zen. Silent illumination, however, is also unique. As a practice it cannot be pigeonholed into distinct sectarian methods, intellectual knowledge, or some kind of reified experience that can be possessed. This program will be based on the writings of Chan master Hongzhi Zhengjue (1091–1157). We will explore several expedient means to cultivate silent illumination on and off the cushion, learning formal seated meditation practice as well as how to cultivate silent illumination in daily life.
