A sesshin is a traditional Zen Buddhist retreat focused on meditation and mindfulness. During a sesshin, participants engage in intensive meditation practice, often lasting several days, to deepen their understanding of Zen teachings. The schedule typically includes periods of zazen (sitting meditation), walking meditation, and chanting, along with meals and rest. These retreats are designed to foster a sense of community and support among practitioners. Participants often follow a strict schedule, which helps cultivate discipline and concentration. Sesshins can be held at Zen centers or monasteries, and they are an essential part of the practice for many Zen Buddhists.
