Buddhism in Japan This period saw the introduction of the two schools that had perhaps the greatest impact on the country: the schools of Pure Land Buddhism, promulgated by evangelists such as Genshin and articulated by monks such as Hōnen, which emphasize salvation through faith in Amitābha and remain the largest Buddhist sect in Japan (and throughout Asia); and Zen, promulgated by monks such as Eisai and Dōgen, which emphasize liberation through the insight of meditation, which were equally rapidly adopted by the upper classes and had a profound impact on the culture of Japan.
Upanishads More than 200 Upanishads are known, of which the first dozen or so are the oldest and most important and are referred to as the principal or main (mukhya) Upanishads.[14][15] The mukhya Upanishads are found mostly in the concluding part of the Brahmanas and Aranyakas[16] and were, for centuries, memorized by each generation and passed down orally. The early Upanishads all predate the Common Era, five[note 6] of them in all likelihood pre-Buddhist (6th century BCE),[17] down to the Maurya period.[18] Of the remainder, 95 Upanishads are part of the Muktika canon, composed from about the last centuries of 1st-millennium BCE through about 15th-century CE.[19][20] New Upanishads, beyond the 108 in the Muktika canon, continued to be composed through the early modern and modern era,[21] though often dealing with subjects which are unconnected to the Vedas.[22]
