Günga Gyaicain is generally known simply as Sa'gya Paṇḍita, a title given to him in recognition of his scholarly achievements and knowledge of Sanskrit. He is held in the tradition to have been an emanation of the Bodhisattva Manjushri, the embodiment of the wisdom of all the Buddhas.

He became known as a great scholar in Tibet, Mongolia, Coastal China and India and was proficient in the five great sciences of medicine, grammar, dialectics and sacred Sanskrit literature as well as the minor sciences of rhetoric, synonymies, poetry, dancing and astrology. He is considered in Tibet to be the fourth "Great Forefather" and sixth Sakya Trizin, and one of the most important figures among the Sakya lineage.
