One of the five vehicles, v. 五乘, that of the five commandments, the keeping of which ensures rebirth in the world of men.

A Dictionary of Chinese Buddhist Terms, William Edward Soothill and Lewis Hodous

人乘===（術語）五乘之一。謂五戒之教。乘此以生於人趣也。

丁福保《佛學大辭典》

人者忍也。於世間違順情境，悉能安忍故也。謂人以三歸五戒為乘，運出四趣，生於人道，故名人乘。（三歸依，歸依佛、歸依法、歸依僧也。五戒者，不殺、不盜、不邪婬、不妄語、不飲酒也。四趣者，修羅趣、餓鬼趣、畜生趣、地獄趣也。）
