Jieshenmi jing; Skt. Sam!dhinirmocana-su^tra. Tib. Dgon%gs-pa n%es-par-h!grol-pa （Sutra on Understanding Profound and Esoteric Doctrine， Sutra of the Explication of the Underlying Meaning）. The singlemost important scriptural source for the doctrines of the Yoga^ca^ra school 瑜伽行派--the rest of its most important texts being treatises. It gives in-depth discussion regarding the nature of the a^laya consciousness 阿赖耶识， the meaning of conscious construction only 唯识， the three natures of reality 三性， the two kinds of meditation 止观， the stages of the bodhisattva path 五位， and the bodies of the Buddha 佛身. It is thought that the sutra was put together around 300 C.E.， a little after the time of Na^ga^rjuna 龙树， during the middle period of Maha^ya^na sutras.
