The Psychobiological Effects of Participation in a One-Month Insight Meditation Retreat

"Retreats at Spirit Rock Meditation Center were led by teams of 6 experienced teachers. Participants practiced noble silence-refraining from eye contact as well as verbal and written communication-except during meetings with teachers. Teachers lead guided Insight meditation practices, as well as meditations on loving-kindness, compassion, empathetic joy, and equanimity. The daily schedule consisted of sitting and walking meditation sessions (30-45 mins) totaling 8-10 hours/day, meals, and short work meditations (sweeping, dishes, etc.). Seated meditation was practiced as a group in a meditation hall with approximately 80 participants. Walking meditation took place in adjoining halls or on the grounds. Participants lived on-site during the retreat and were provided with a vegetarian diet."
