Well Explained Reasoning (Skt. Vyākhyāyukti; Tib. རྣམ་པར་བཤད་པའི་རིགས་པ་, Wyl. rnam par bshad pa'i rigs pa) — a work by Vasubandhu that sets out the principles of exegesis or hermeneutics and teaches how to interpret and explain the content of a sutra. It has five chapters, and in the fourth Vasubandhu refutes the assertion that the Great Vehicle cannot be considered as Buddhism.<ref>Skilling, Peter. Vasubandhu and the Vyākhyāyukti Literature, in the Journal of the International Association of Buddhist Studies, Volume 23, Number 2, 2000, page 334-335.</ref>
It states that sutras are to be explained according to:
their purpose (Skt. sūtrānta-prayojana; Wyl. mdo sde 'i dgos pa)
their summarized meaning (Skt. piṇḍārtha; Wyl. bsdus pa'i don)
the meaning of the words (Skt. padārtha; Wyl. tshig gi don)
their sequence and connection (Skt. anusaṃdhi; Wyl. mtshams sbyar ba)
objections and refutations (Skt. codyaparihāra; Wyl. brgal ba dang lan)
These five topics are discussed in the first four chapters. The fifth chapter is an appendix on the benefits of listening to the dharma.
All three texts, the text itself and the two related texts, at present only exist in Tibetan translation in the Mind Only section of the Tengyur.
