The practice of Rinzai Zen involves a variety of disciplines and activities that are intended to help practitioners awaken to their true nature and to progress along the spiritual path. Here is a list of some key practices:

• Meditation: Rinzai Zen practitioners engage in seated meditation (zazen) as a way to still the mind and cultivate a sense of presence and clarity.
• Koans: Rinzai Zen is known for its use of koans, which are Zen puzzles or paradoxes that are used to help practitioners awaken to their true nature. Koans are often studied and meditated upon as a way to break through the limitations of the ego and to see beyond the dualistic thinking of the ordinary mind.
• Chanting: Rinzai Zen practitioners may engage in chanting as a way to focus the mind and to cultivate a sense of devotion and connection to the teachings.
• Study: Rinzai Zen practitioners may study the teachings of the tradition, as well as the writings of Zen masters, in order to deepen their understanding of the spiritual path.
• Community engagement: Rinzai Zen is often practiced in a community setting, such as at a Zen temple or monastery. Participating in a community of practitioners can help to support and inspire one's practice.
