Yogācārabhūmi-śāstra, also known as "Discourse on the Stages of Yogic Practice" is the encyclopaedic and definitive text of the Yogācāra school of Buddhism. It is thought to have been composed in India between 300 and 350 CE. The complete work comprises five major sections: the seventeen levels (bāhu-bhūmi) which covers the entire range of mental and spiritual levels in Buddhism according to Mahāyāna; the Compendium of Definitions (viniścaya-samgraha) which discusses and explicates aspects of the bāhu-bhūmi portion; the Compendium of Exegesis (vivarana-samgraha), a manual of hermeneutical and exegetical techniques; the Compendium of Synonyms (paryāya-samgraha) defining many of the various strings of quasi-synonymical expressions found in the Agamas; the Compendium of Topics (vastu-samgraha) summarizing and explainin the key topics of each sūtra contained in the Samyukta-āgama; and the Compendium of the Vinaya (vinaya-samgraha). The Chinese version also contains a Compendium of Abhidharma, missing from the Tibetan translation.
