Increasing by One Āgama Sutra ［増一阿含経］ (Chin Tseng-i-a-han-ching;  Zōichi-agon-gyō): One of the four Chinese Āgama sutras. The Increasing by One Āgama Sutra consists of 471 smaller sutras in 52 sections. It was translated and compiled in 51 volumes by Samghadeva, a monk from Kashmir, in 397. This Chinese text corresponds to the Pali text Anguttara-nikāya, and categorizes various doctrines into eleven groups, numbered one through eleven, each of which contains doctrines whose name or description contains that number. For example, the third group includes doctrines such as the three treasures and the three categories of action; the fourth group includes the four noble truths, the four forms of birth, etc. This incremental organization of its contents is the source of the sutra’s title, “Increasing by One.”
