E. Gene Smith also judged that Mipham's greatest contribution was "in his brilliant and strikingly original commentaries on the Indian treatises." Prior to Mipham, Nyingmapa scholars "had seldom written detailed pedagogical commentaries on the "śāstras" of exoteric Buddhism." Until his time the colleges or shedra associated with the great Nyingma monasteries of Kham, such as Dzogchen, Shechen, Kathog, Palyul and Tarthang lacked their own exegetical commentaries on these exoteric Mahayana "śāstras", and students commonly studied Gelug commentaries on these fundamental texts. Grounding himself in the writings of Śāntarakṣita, Rongzom Chokyi Zangpo, and Longchenpa, Mipham produced a whole array of brilliant exegetical commentaries on the great Indian philosophical systems and texts that clearly articulated a Nyingma orientation or view.
