“Tantric Sutra” is one of the four major sutras of Kumbum Monastery, and its free translation is “the great paradise of Tantra with virtue”. It is a Tibetan-style building with a flat roof on the second floor. The roof is decorated with gold-plated roofs, Dharma pillars, Dharma wheels, golden deer, etc. The exterior walls are inlaid with whip hemp walls, hidden windows, bronze mirrors, and two prayer flag poles on both sides of the door. The monastery was founded by Sina Leba Gyatso in 1649 AD in accordance with the decree of the fourth Panchen Lama Lobsang Chokyi Gyaltsen. It was later rebuilt and expanded several times to its current scale. The monks who study in tantric scholastic schools specialize in the deities of Guhyasamadhi Vajra, Chakrasamvara, and Yamantaka Vajra. They pay attention to practice, and confer “Orampa” Tantric doctorate degrees to those who are excellent in various fields. The murals on the upper and lower floors of the cloister in the courtyard are “Thousand Buddhas of the Wise Kalpa”. On both sides of the sutra hall door are the three statues of Tsongkhapa’s master and disciples, the Twenty-One Mothers, the five manifestations of Tsongkhapa, twelve deeds in the life of the Buddha, and four Statue of the Great King. The niches in the sutra hall enshrine Gyasya Vajra, Chakrasamvara, Yamantaka and the Mandala respectively. The main deity is the 16-year-old Maitreya Buddha and his two attendants. Surrounded by Atisha, Master Tsongkhapa’s tantric disciple Jieshirao Sangge, Sakyamuni Buddha, Master Tsongkhapa and the eight great Bodhisattvas.
