Tiān-qīn púsà 天親菩薩 (*Vasubandhu, “Kinsman-of-the-Vasus”; conventionally c. 320–400 CE), Indian Buddhist master, the most consequential single Buddhist philosopher of the post-Aśoka period. Younger brother of Asaṅga, converted by him from Sarvāstivāda Abhidharma scholasticism to Mahāyāna Yogācāra. Per Paramārtha’s Pó-sǒu pán-dòu zhuàn 婆藪槃豆傳 (T2049) and Tibetan biographies, Vasubandhu was born in Puruṣapura (Peshawar, Gandhāra) and was the principal Sarvāstivāda Abhidharma master of his generation, author of the Abhidharmakośa (the foundational Sarvāstivāda Abhidharma compendium); after his conversion to Mahāyāna by Asaṅga he composed the canonical Yogācāra treatises: the Triṃśikā (Wéishí sānshí sòng), the Viṃśatikā, the Madhyānta-vibhāga-bhāṣya, and many others.
The Chinese name 天親 (“Heaven-Kinsman”) is a calque-translation of Vasu-bandhu; the alternative 世親 (“World-Kinsman”) is the more usual modern form. The Indic name 婆藪槃豆 (Pósǒu pándòu) is the transliteration. The name is used variably across the Chinese canon.
His surviving Chinese-translation works are extensive: the Abhidharmakośa (T1558–60); the Yogācāra treatises Triṃśikā (T1586) and Viṃśatikā (T1590); the Daśabhūmika-vibhāṣā commentary (T1521); [[KR6c0032|T1511 Vajracchedikā-prajñāpāramitā-sūtra-śāstra]]; and many others.
