戒賢 (529–645) (Skt; Jpn Kaigen)
An Indian scholar of the Consciousness-Only (Skt Vijnanavada) school. Born to the royal family of the kingdom of Samatata in eastern India, he studied the Consciousness-Only doctrine under Dharmapala at Nalanda Monastery and was widely known as an outstanding scholar. According to The Biography of the Tripitaka Master of Ta-tz'u-en-ssu Temple, when the Chinese priest Hsüan-tsang visited the monastery to study in the early seventh century, Shilabhadra taught him the doctrines of the Consciousness-Only school. Hsüan-tsang then brought them back to China, thereby establishing the basis of the Dharma Characteristics (Chin Fa-hsiang; Jpn Hosso) school.
