Hanshan Deching, renowned as one of the four Buddhist masters in the late Ming dynasty, gave equal weight to Buddhist doctrines and meditation. The eminent monk focused on the Huayen school of dogmas and the meditation practice leading to true enlightenment. The gatha Guan Xin Ming from him, its content being doctrinal essentials for meditation practice, addresses the involvement of body and mind in the practice and the critical importance of understanding the role of mind (the heart).
