This particular set of thangkas relates to the various teachings and travels of Tsong Khapa (1357-1419), founder of the Gelug tradition of Tibetan Buddhism. Born in the Amdo region of Eastern Tibet as Lobzang Dragpa, Tsong Khapa, popularly referred to as Je Rinpoche, received his monk's vows from the fourth Karmapa Rolpay Dorje. After travelling to Central Tibet he studied with Sakya, Kagyu and Nyingma masters, showing a special fondness for the Sutra-based teachings of Atisha and the earlier Kadampa tradition. With the founding of Ganden monastery in 1409, the Gelugpa ('way of virtue') school was born. This biographical set of paintings includes scenes from his youth and early career, such as his debates and teaching of logic at the Aye Monastery and his visits to Densatil, Gungthang, and Drikung monasteries (a-c).
Later scenes depict Tsong Khapa's meeting with the Nyingma monk Lodrag Khenchen as a visual allegory of Manjushri encountering Vajrapani (c), and the founding of Ganden Monastery in 1409 (h-i). The last thangka, painted with an elaborate palace complex, shows Tsong Khapa entering Tushita Heaven upon his death (j).
