Vasubandhu，梵名婆藪槃豆，又曰婆修槃陀，譯曰天親，新作伐蘇畔度，譯曰世親。波藪譯曰世天，毘紐天之異名也。以父母求世天親愛而名。或言為天帝之弟，故名天親，婆藪槃豆傳曰：「婆藪槃豆者，北天竺富婁沙富羅國（譯曰丈安國）人，佛滅後九百年而出，兄弟三人，皆名婆藪槃豆，長兄別稱阿僧伽（譯曰無著），小弟別稱比鄰持跋婆（比鄰持母名，跋婆譯曰兒），中子獨以通名稱。初於阿踰闍國薩婆多部出家，研學小乘既通大毘婆沙論之義，為眾講之，一日作一偈，共作六百偈，稱為俱舍論。後用無著之示誨，懺悔小執之非，欲斷舌謝其罪。無著云：汝既以舌誹謗大乘，更以此舌讚大乘可也。於是造唯識論等諸大乘論，弘宣大教，壽八十，寂於阿踰闍國。」付法藏傳六曰：「尊者闍夜多臨滅度時，告比丘婆修槃陀：無上妙法，今付屬汝，汝當至心護持。婆修盤陀受教，解一切之修多羅，廣化眾生。」百論序疏曰：「婆藪云天親，天親者天帝之弟也。生於閻浮提而伏修羅，是割那舍闍人，云丈夫國。原為小乘學，通五百部之小乘。兄阿僧伽是大乘人，見弟盛弘小乘而覆大道，特現病曰：汝罪過深重，我為之病。弟曰若爾則是舌之過，當斷舌。曰：不如更造大乘論而宣流大道。於是作五百部之大乘論，時人呼為千部論主。」西域記五曰：「伐蘇畔度菩薩，唐言世親，舊曰婆藪槃豆。譯曰天親，誤也。」
Vasubandhu, 伐蘇畔度; 婆藪槃豆 (or 婆修槃豆) (or 婆修槃陀) 'akin to the gods ', or 世親 'akin to the world'. Vasubandhu is described as a native of Puruṣapura, or Peshawar, by Eitel as of Rājagriha, born '900 years after the nirvana', or about A. D. 400; Takakusu suggests 420-500, Peri puts his death not later than 350. In Eitel's day the date of his death was put definitely at A. D. 117. Vasubandhu's great work, the Abhidharmakośa, is only one of his thirty-six works. He is said to be the younger brother of Asaṅga of the Yogācāra school, by whom he was converted from the Sarvāstivāda school of thought to that of Mahāyāna and of Nāgārjuna. On his conversion he would have 'cut out his tongue' for its past heresy, but was dissuaded by his brother, who bade him use the same tongue to correct his errors, whereupon he wrote the 唯識論 and other Mahayanist works. He is called the twenty-first patriarch and died in Ayodhya.
