The Triṃśikā-vijñaptimātratā (Sanskrit; traditional Chinese: 唯識三十論頌; pinyin: Wéishí sānshí lùn sòng; Japanese: Yuishiki sanjūronju; Korean: 유식삼십송), also known simply as the Triṃśikā or occasionally by is English translation Thirty Verses on Manifestation Only, is a brief poetic treatise by the Indian Buddhist monk Vasubandhu. It was composed in the 4th or 5th century CE and became one of the core texts for the Yogācāra school of Mahāyāna Buddhism. In it he touches on foundational Yogācāra concepts such as the storehouse consciousness, the afflicted mental consciousness, and the three natures, among others. Together with the Vimśatikā form a standard summary of Vasubandhu's understanding of Yogācāra.
