Zen

Zen emphasizes the attainment of enlightenment and the personal expression of direct insight in the Buddhist teachings. As such, it de-emphasizes mere knowledge of sutras and doctrine and favors direct understanding through zazen and interaction with an accomplished teacher. The teachings of Zen include various sources of Mahāyāna thought, especially Yogācāra, the Tathāgatagarbha Sutras and Huayan. The Prajñāpāramitā literature and, to a lesser extent, Madhyamaka have also been influential.
