Asanga

Asaṅga (Tibetan: ཐོགས་མེད།, Wylie: thogs med, traditional Chinese: 無著; ; pinyin: Wúzhuó; Romaji: Mujaku) was a major exponent of the Yogacara tradition in India, also called Vijñānavāda. Traditionally, he and his half-brother Vasubandhu are regarded as the founders of this school. The two half-brothers were also major exponents of Abhidharma teachings.

Asaṅga was born as the son of a Kṣatriya father and Brahmin mother in Puruṣapura (present day Peshawar in Pakistan), which at that time was part of the ancient kingdom of Gandhāra. Current scholarship places him in the fourth century CE. He was perhaps originally a member of the Mahīśāsaka school or the Mūlasarvāstivāda school but later converted to Mahāyāna. According to some scholars, Asaṅga's frameworks for abhidharma writings retained many underlying Mahīśāsaka traits.André Bareau writes:

[It is] sufficiently obvious that Asaṅga had been a Mahīśāsaka when he was a young monk, and that he incorporated a large part of the doctrinal opinions proper to this school within his own work after he became a great master of the Mahāyāna, when he made up what can be considered as a new and Mahāyānist Abhidharma-piṭaka.
