Dharma-dharmata-vibhaga
Dharma-dharmatā-vibhāga(Chinese:辩法与法性论） (Distinguishing Phenomena and Pure Being) is a short Yogācāra work, attributed to Maitreya-nātha, 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. However, the Sanskrit original was reported to exist in Tibet during the 1930s by the Indian Buddhologist and explorer, Rahul Sankrityayan.
