Zen, known as Chan in China, Thiền in Vietnam, and Seon in Korea, is a school of Mahayana Buddhism that emerged in China during the Tang dynasty. It developed by integrating Indian Mahayana Buddhist philosophies, such as Yogacara and Madhyamaka, with Chinese Taoist thought, particularly Neo-Daoism. Traditionally, its transmission to China is attributed to the monk Bodhidharma. The core of Zen practice revolves around meditation, aiming for direct realization of one's innate Buddha-nature and expressing this insight in daily life. While some Zen traditions de-emphasize doctrine and ritual in favor of direct experience and interaction with a master, many also incorporate traditional Buddhist practices like chanting, precepts, and scriptural study.

Zen's philosophical underpinnings include the concept of Buddha-nature, intrinsic enlightenment, and sudden awakening. It draws upon various Buddhist texts and schools, including the Sarvāstivāda meditation practices, Mahayana teachings on the bodhisattva, Yogachara, Tathāgatagarbha literature, and the Huayan school. The influence of Prajñāpāramitā and Madhyamaka thought contributes to Zen's often apophatic and unconventional rhetoric. The term 'Zen' itself derives from the Sanskrit word 'dhyāna,' meaning meditative state or contemplation.

Zen Buddhism, originating as the Chan school in Tang dynasty China, represents a synthesis of Indian Mahayana Buddhism and Chinese Taoist thought. Its foundational philosophies include Yogacara and Madhyamaka, blended with Neo-Daoist ideas. The tradition is conventionally linked to Bodhidharma, an Indian or Central Asian monk who is said to have brought Chan to China. From China, the tradition spread, evolving into Thiền in Vietnam, Seon in Korea, and Zen in Japan. The school was also known as the 'Buddha-mind school,' referencing the enlightened mind of the Buddha or the inherent pure mind within all beings.

Central to Zen is the practice of meditation, particularly sitting meditation (zazen in Japanese, zuòchán in Chinese). The ultimate aim is direct insight into one's own Buddha-nature, leading to personal realization and compassionate action. While some Zen lineages prioritize direct experience and interaction with a teacher, often depicted as unconventional, over formal study and ritual, most schools also maintain traditional Buddhist practices. These include chanting, adherence to precepts, walking meditation, rituals, monastic life, and the study of scriptures. Zen teachings emphasize intrinsic enlightenment and sudden awakening, drawing from a wide array of Buddhist philosophical and meditative traditions.

Early Chan meditation drew from Indian Dhyāna sutras translated into Chinese, focusing on practices like mindfulness of breathing and contemplation. While some scholars note that early Chan often integrated classic Buddhist meditation methods, unique Zen approaches also emerged. These include practices like 'maintaining mind' or 'viewing the mind,' which direct attention to the nature of awareness itself, equating it with Buddha-nature. This direct and sudden approach, sometimes described as 'tracing back the radiance,' aims for immediate realization without extensive preliminary exercises. Simultaneously, Zen discourse often employs concepts like 'no-mind' (wuxin) and emptiness, drawing from Madhyamaka philosophy to avoid reifying mental concepts and to emphasize the non-dualistic nature of reality.
