Mahayanasamgraha is one of the most important texts of the Yogacara School of Mahayana Buddhism. In this text, its author, Asanga, developed and systematized the Yogacara philosophy and praxis. This volume presents an English translation of Mahayanasamgrahas third chapter which discusses the bodhisattvas entrance onto the defining characteristics of what is to be known, i.e. the realization of vijnapti-matrata. The translation is based on the Tibetan text edition by utilizing and consulting all available Tibetan editions-sDe dge, Co ne, Peking, sNar, thang, Taipei, Lamotte, Yamaguchi and Nagao. This volume also contains English translation and Tibetan texts of the selected passages in the commentaries of the text, i.e. Mahayanasamgraha-bhasya by Vasubandhu and Mahayana-Samgrahopanibandhana by Asvabhava. The translation of the text in this volume aims to advance a scholarly under-standing of praxis, and the relation of the practical and philosophical theories described in the third chapter of Mahayanasamgraha and its commentaries.
