Zen...

Zen is a school of Mahāyāna Buddhism, referred to in Chinese as Chán. Chán is itself derived from the Sanskrit Dhyāna, which means "meditation" ..

Zen emphasizes experiential Prajñā—particularly as realized in the form of meditation known as zazen—in the attainment of awakening, often simply called the path of enlightenment. As such, it de-emphasizes both theoretical knowledge and the study of religious texts in favor of direct, experiential realization through meditation and dharma practice.

The establishment of Zen is traditionally credited to the Southern Indian Pallava prince-turned-monk Bodhidharma, who is recorded as having come to China to teach a "special transmission outside scriptures" which "did not stand upon words". The emergence of Zen as a distinct school of Buddhism was first documented in China in the 7th century CE. It is thought to have developed as an amalgam of various currents in Mahāyāna Buddhist thought—among them the Yogācāra and Madhyamaka philosophies and the Prajñāpāramitā literature—and of local traditions in China, particularly Taoism and Huáyán Buddhism. From China, Zen subsequently spread southwards to Vietnam and eastwards to Korea and Japan........From Wikipedia
