The article analyzes the figure of Indian philosopher Vasubandhu (ca. S. IV), one of the most important representative of the vijñānavāda school of mahāyāna Buddhism. After a brief account on the legendary biography of Vasubandhu and other members of his school, the article focuses on the understanding of two of his seminal works: Trimśikā and Trisvabhāvakārikā through the concepts of vijñāna (showing the different meanings of this widely used concept in Buddhist thought), ālayavijñāna (store consciousness), vāsanā (mental trace), parikalpa (imagination) (...) and trisvabāva (three natures): parikalpita (imaginative), paratantra (dependent) and parinispanna (consummated). It also establishes the links between Vasubandhu and the nāgārjuna’s doctrine of śūnyatā and the Buddhist practice of puöya-praöidhana (dedication of merit) and bodhicitta (thought of awakening), showing, in a coherent fashion, the practical aspects of this philosophy of mind.
