Dharma-dharmatā-vibhāga (Sanskrit). A short Yogācāra work, attributed to Maitreyanātha, which discusses the distinction and correlation (vibhāga) between phenomena (dharma) and reality (dharmatā). The work exists in both a prose and a verse version and survives only in Tibetan translation although a Sanskrit original was reported by Rāhula Sāṇkṛtyāyana to exist in Tibet during the 1930s.
