Vasubandhu ［世親・天親］ (n.d.) (; Seshin or Tenjin): A Buddhist scholar in India thought to have lived around the fourth or fifth century. He is known as the author of The Dharma Analysis Treasury. Vasubandhu was born to a Brahman family in Purushapura of Gandhara in northern India. He had an older brother, Asanga. In the central Indian city of Ayodhyā, he studied the doctrine of the Sarvāstivāda school and lectured on The Great Commentary on the Abhidharma, the primary text of that school. He compiled these lectures as The Dharma Analysis Treasury, which presents a comprehensive discussion of the Sarvāstivāda thought. Thus he became the undisputed master of Hinayana philosophy in India at the time. Vasubandhu at first criticized Mahayana, but later converted to it through the influence of his brother Asanga, whom he assisted thereafter in promoting the Yogāchāra, or Consciousness-Only, school of Mahayana. Vasubandhu is said to have written a thousand works, five hundred related to Hinayana and five hundred to Mahayana. Among those that have survived are The Twenty-Stanza Treatise on the Consciousness-Only Doctrine, The Treatise on the Ten Stages Sutra, The Treatise on the Lotus Sutra, The Commentary on “The Summary of the Mahayana,” and The Treatise on the Buddha Nature. He is counted as the twentieth of Shakyamuni’s twenty-three, or the twenty-first of his twenty-four, successors.
