What explains the world as experienced?
A world experienced as subjects confronting objects seems to require external objects. Vasubandhu asks whether that inference is justified. His investigation belongs to a Buddhist effort to undo mistaken attachments and explain karmic continuity without a permanent self.
Sources: 5Counterexamples before a positive explanation
The Twenty Verses considers objections from the regular places, times, shared character and effects of experience. Dreams challenge the inference from a structured appearance to an external object. Such counterexamples initially show that the realist’s inference is not compulsory; they do not alone establish a complete alternative account of experience.
Sources: 4Why is experience shared?
A critic can allow private dreams but ask why several beings experience a common world. Vasubandhu appeals to karmic conditioning and examples of shared appearances. The reader should ask whether accepting that background makes the alternative explanation more convincing, and how someone outside it could evaluate the argument.
Sources: 5Verse, commentary and interpretation
The Treasury organizes scholastic positions and criticizes some of them in commentary. The shorter Yogācāra works select different explanatory tasks. Scriptural interpretation also matters: a teaching may address a learner provisionally. Intellectual development cannot be read directly from a simple list of works when dates and authorship remain contested.
Sources: 5A biography that cannot bear exact dates
Later sources associate Vasubandhu with Gandhāra and with Asaṅga. Competing chronologies and the debate about more than one author counsel against the old profile’s precise-looking birth and death years. The interval displayed here is explicitly disputed, and detailed claims of personal patronage are withheld.
Sources: 5What does “representation-only” claim?
Interpreters dispute how appropriately to call Vasubandhu an idealist. The label can help identify a denial of external objects, but can obscure the critique of subject–object construction and the religious task of transformation. “Everything is my private fantasy” is particularly misleading: the account includes multiple conditioned streams of experience.

Must structured experience have an external object?
c. fourth–fifth century CE · approximate
Representation-only questions whether the subject and object appearing in cognition exist as they appear. Vasubandhu combines replies to realist objections with an account of conditioned experience. His target is bound to Buddhist non-self and liberation, and should not be reduced to an assertion that one individual invents the world.

Sources: 5Intellectual setting
Vasubandhu’s works participate in monastic debates about Abhidharma analysis, scriptural interpretation and the Mahāyāna path. Later biographies narrate a turn toward Yogācāra associated with Asaṅga; their chronology and the unity of the attributed corpus remain debated.
Key ideas
Vijñaptimātra (representation-only)
In short treatises such as the "Viṃśatikā" and "Triṃśikā," Vasubandhu argued that the perceived world of objects is exhaustively explained by the ripening of "seeds" (bīja) stored in an underlying store-consciousness (ālayavijñāna), so that no external material substrate need be posited to account for ordinary experience.
Momentariness and the critique of Vaibhāṣika realism
In the "Abhidharmakośa," Vasubandhu catalogued and criticized rival Buddhist positions on causation and time, defending a rigorous doctrine of momentary existence (kṣaṇikatva) against the Vaibhāṣika thesis that the constituents of experience (dharmas) exist substantially across past, present, and future.
Legacy
The "Abhidharmakośa" became the standard scholastic textbook of Buddhist philosophy across India, Tibet, and East Asia, while Vasubandhu's Yogācāra treatises, transmitted and commented on by Sthiramati, Dharmapāla, and Xuanzang, founded the Yogācāra ("Consciousness-Only") tradition that shaped Buddhist epistemology and psychology for over a millennium.
