Chan is a way of life that encourages mental clarity, compassion to all beings, and wisdom that comes from putting down our baggage and neuroses and seeing things as they really are.
Meditation is the fundamental practice. Chan actually means meditation. There are two aspects. Calming the mind and insight into the nature of the mind. Without calming and stabilizing the mind, insight is very difficult. Without insight, calming is just relaxation.
Calming and insight practices lead to depth and clarity.
Mindfulness of Breathing (anapanasati) is the practice of being present with our experience by using the breath as an anchor.
Silent Illumination (mozhao) is the practice of being fully present with our experience, without an anchor.
This is the tradition I teach in. If you want to learn more, sent me a message.
