Vasubandhu

Vasubandhu (c. 4th–5th century CE) was an Indian Buddhist monk and one of the most important philosophers in the Mahayana tradition. Initially a master of the realist Abhidharma systems (author of the encyclopedic Abhidharmakosha), he was, according to tradition, converted by his brother Asanga to the Yogacara (“yoga practice”) school, after which he produced its most influential concise statements: the Vimsatika (Twenty Verses) and the Trimsika (Thirty Verses).

Vasubandhu’s contribution is the rigorous formulation of the Vijnaptimatra—“representation-only” or “mind-only”—turn, one of the deepest philosophical roots of any “mind constructs reality” doctrine. In the Vimsatika he argues that what we take to be an independent external world is more coherently understood as a structure of cognitions, defending this against objections by analyzing dreams, collective perception, and causation.

In the Trimsika he supplies the positive model: consciousness is layered, and the subject–object duality we experience is generated by these layers—most distinctively the alaya-vijnana or “store-consciousness,” a substratum that carries karmic seeds and ripens them into experience.

The consequence is that transformation is fundamentally a restructuring of cognition—a “revolution of the basis”—rather than the manipulation of an external world. This cognitive, perception-first framework is a foundational ancestor of later idealist and “reality is mind-made” currents, flowing through Zen and Tibetan Buddhism and resonating with modern constructivist and consciousness-centered manifestation thought.
