Khedrup Gelek Palsang (1385–1438), well known as Khedrup Je, was one of the main disciples of Tsongkhapa (1357–1419), founder of the Geluk school of Tibetan Buddhism. Khedrup was already a learned scholar in the Sakya school when he met Tsongkhapa, having trained with the master Rendawa Shönü Lodrö (1349–1412). His eleven volumes of collected works contain key commentaries on philosophy such as the one here, but also many influential works on tantra. He also composed the main biography of Tsongkhapa. His literary flair and skill in argumentation continue to be emulated in the Geluk school to this day.
Gyaltsab Je (1364–1432) was born in the Tsang province of central Tibet. He was a famous student of Je Tsongkhapa, and became the first Ganden Tripa (throne holder) of the Gelug tradition after Je Tsongkhapa's death. He also studied with Rendawa Zhonnu Lodro (red mda' ba gzhon nu blo gros, 1349–1412). Gyaltsab Je was a prolific writer; one of his most famous texts is a commentary of Shantideva's A Guide to the Bodhisattba's Way of Life. Lodro Tenpa, the seventh Ganden Tripa, was his student.
