The Abhidharma-samuccaya (Sanskrit; ; English: "Compendium of Abhidharma") is a Buddhist text composed by Asaá¹ ga. The Abhidharma-samuccaya is a systematic account of Abhidharma. According to J. W. de Jong it is also "one of the most important texts of the YogÃÂcÃÂra school." According to Frauwallner, this text is based on the Abhidharma of the Mahëà ÂÃÂsaka tradition.
The text exists in Chinese, Tibetan and a reconstructed Sanskrit version. Its Taishà  Tripiá¹Âaka (Chinese Canon) number is 1605. In the Tibetan Tengyur, it is number 4049 in the Derge Tengyur and 5550 in the Peking Kangyur.
According to Traleg Rinpoche, the Abhidharma-samuccaya is one of Asanga's most essential texts and also one of the most psychologically oriented. It provides a framework, as well as a general pattern, as to how a practitioner is to follow the path, develop oneself and finally attain Buddhahood. It presents the path according to the YogÃÂcÃÂra school of Mahayana Buddhism.
According to de Jong, "whilst the MahÃÂyÃÂnasaá¹Âgraha is a compendium of specifically MÃÂhÃÂyanist teachings of the YogÃÂcara school, the Samuccaya is a systematic guide to the Abhidharma section of the doctrinal system of the said school." According to Dan Lusthaus, Asaá¹ ga, "was primarily an Agamist, i.e., one who based himself on the ÃÂgamas. This text served as his overview of abhidharma from his developing Yogacaric perspective."
The Abhidharmasamuccaya survives in full Chinese (by Xuanzang) and Tibetan translations (by Yeshe de). About two fifths of the Sanskrit text was recovered in Tibet by RÃÂhula Saá¹ ká¹Âtyayana in 1934 and Pralhad Pradhan produced a reconstructed Sanskrit version of the full text in 1950 (basing himself on the Sanskrit material as well as the Chinese and Tibetan translations). Walpola Rahula translated this reconstruction into French in 1971.
Contemporary scholar Achim Bayer asserts that different sections of the Abhidharma-samuccaya might be heterogenous. For example, the important term ÃÂlayavijñÃÂna ("Store-house Consciousnesses") appears not more than six times, with all six occurrences in the "Laká¹£aá¹Âasamuccaya" section, i.e. in the first third of the work.
According to Walpola Rahula the Abhidharmasamuccaya is more faithful to the presentation of the dhyÃÂnas found in the suttas than the Theravada Abhidhamma texts.
