Asaṅga. Also translated as 無着 and transcribed as 阿僧伽. A great exponent of the Yogācāra School who was a native of Gandhāra in north India in the fourth century CE. Born as a Brahmin's son, he first followed Hīnayāna but was later converted to Mahāyāna. He composed numerous discourses on the Yogācāra philosophy and practice, including the Mahāyāna-saṃgraha-śāstra 攝大乘論 and Prakaranāryavāca-śāstra 顯揚聖教論. In the Tibetan tradition, he is also attributed with the authorship of the Yogācārabhūmi-śāstra 瑜伽師地論. Myth says that he often visited Tuṣita Heaven to receive the teaching from Maitreya. His younger brother Vasubandhu 世親 further developed Yogācāra doctrine.

Unattached, not in bondage to anything. Name of Asaṅga, brother of Vasubandhu, and others.

１．沒有執著的意思。２．菩薩名，佛滅九百年間出生於健陀羅國（在克什米爾之西），先從彌沙塞部出家，後信大乘，每夜昇兜率天，聽彌勒菩薩講瑜伽師地論，白天則對大眾開示，為法相宗之祖。

陳義孝編, 竺摩法師鑑定, 《佛學常見辭彙》

無著者，謂阿難被佛徵詰，心不在中間。則又計之，一切無著，名之為心。佛又問云：汝言不著名為心者，如世間虛空水陸飛行，一切物象，汝心不著。此等物象，為有為無。若言無者，則同龜毛兔角，云何更有不著之物，而言不著。若言有者，物在則心亦在，云何無著。故云一切無著，名覺知心，無有是處。
