Legacy Teachings Sutra ［遺教経］ (Chin I-chiao-ching; Yuikyō-gyō): Also known as the Buddha’s Legacy Teachings Sutra. A sutra translated into Chinese by Kumārajīva in the early fifth century. It purports to have been preached by Shakyamuni Buddha as his final instruction to his disciples under the sal trees just before his death. This sutra says that, after the Buddha’s death, one should observe the precepts in order to control the five sense organs and regulate the mind, and devote oneself to Buddhist practice without succumbing to laziness and sloth. Though an extremely short sutra, Kumārajīva’s translation of it is regarded as one of the best among Chinese sutra translations because of its polished style and excellent wording. The Legacy Teachings Sutra was widely favored and read by many people, and a number of commentaries on it were produced. The Zen school, in particular, values this sutra.
