Run by acclaimed author Jack Kornfield, Spirit Rock hosts retreats involving 30 to 100 or more participants. Most of the retreat is held in silence, and retreat participants do not speak to one another. Writing and reading are also discouraged, so that participants can better stay with their own present experience as it unfolds moment to moment. In this silent and mindful environment, awareness sharpens, the body quiets, the mind clears, and space opens for insight and understanding to unfold. Kornfield is credited for popularizing Buddhism and meditation in the U.S. through numerous books including: A Path with Heart; Buddha’s Little Instruction Book; Teachings of the Buddha; Seeking the Heart of Wisdom; Living Dharma; A Still Forest Pool; After the Ecstasy, the Laundry; The Art of Forgiveness, Lovingkindness and Peace; The Wise Heart: A Guide to the Universal Teachings of Buddhist Psychology; and Bringing Home the Dharma: Awakening Right Where You Are.
