What is "mahayana-sutra-alamkara-karika"

Mahāyāna Sūtrālamkāra kārikā (, "The Adornment of Mahayana sutras") is a major work of Buddhist philosophy attributed to Maitreya-nātha as dictated to Asanga. The text, written in verse, presents the Mahayana path from the Yogacara perspective. It comprises twenty-two chapters with a total of 800 verses and shows considerable similarity in arrangement and content to the Bodhisattvabhūmiśāstra, although the interesting first chapter proving the validity and authenticity of Mahāyāna is unique to this work. Associated with it is a prose commentary (bhāsya) by Vasubandhu and several sub-commentaries by Sthiramati and others; the portions by Maitreya-nātha and Vasubandhu both survive in Sanskrit as well as Tibetan, Chinese, and Mongolian translations.
