Asanga and Vasubandhu, two 5th century Indian brothers instrumental in founding the Hossō 法相 school of Buddhism. Asanga (Jp: Muchaku 無著, also written 無着 and read Mujaku, lit. "Unattached") and Vasubandhu (Jp: Seshin 世親, lit. "Akin to the world"), from Peshawar, were originally Hinayanists but became seminal theorists in the Mahayana tradition. Asanga advocated the theory of conciousness-only, yuishiki 唯識 (Sk: vijnanamatra) and the importance of yogic medication in his Treatise on Yoga, Yugaron 瑜伽論 (Sk: Yogacharyabhumi), and is considered the founder of the Hossō school as well as one of the Five Patriarchs of the Kegon 華厳 sect. Vasubandhu authored the Abhidharmakosa Kusharon 倶舎論 and formed the basis of the Kusha 倶舎 sect, which was appended to the Hossō school in Japan. He is also associated with the Sukhavati-vyuha, Jōdoron 浄土論 a key theoretical tract in the development of Pure Land Jōdo 浄土 Buddhism, which inspired Tanluan (Jp: Donran 曇鸞; 476-542) and Shantao (Jp: *Zendō 善導; 613-81). Thus Vasubandhu is considered one of the Seven Patriarchs of Jōdoshin 浄土真 sect. The wooden sculpture portraits of Asanga and Vasubandhu by Unkei 運慶 (1151-1223) from 1208-12 at Kōfukuji *Hokuendō 興福寺北円堂 in Nara are two high points in Kamakura period sculpture.
