The glorious legendary hero, King Gesar Ling is a Good of War. Though he has the appearance of a wrathful military leader, from a religious perspective Gesar is regarded as an emanation of enlightened compassion. As such he is invoked in this temple for his aid and support against external as well as inner perils. During his last earthly existence he was the ruler of the Kingdom of Ling in northwest Tibet and today he could appear anywhere at any time. Gesar fought for good and Buddhism and freed human beings from the clutches of evil demons. He is the right person to protect Trongsa Dzong, be it against real enemies as in past or against all obstacles to a life of harmony.
Gesar Ling is presented in several different forms within his temple. His statue stands in the three-dimensional mandala. While a life-size figure provides him with an earthly body. Mural painting relates his exploits, depicting Gesar in the nine-part armour of the gods of war.
A monk from the Dzong is exclusively dedicated to the veneration of Gesar. Each day he brings offerings and asks for the protection of the Dzong, the province, the whole world, and the universe.
