The three-storied Lhakhang, situated on a generous five-acre plot provided by the government, represents a significant cultural and spiritual landmark in its community. Constructed in a traditional Bhutanese architectural style, the Lhakhang is dedicated to Guru Nangsi Zilnon, with the main deity enshrined on the ground floor in the Trulku Lhakhang. Flanking Guru Rinpoche are statues of his consorts, Lhacham Mendral Rawn and Khando Yeshi Tshogyel, along with Dorsem Yab Yum and an image of Kuenkhen Longchen Rabjam, the first lam of Tharpaling Dratshang in Bumthang.
The initiative to build this Lhakhang was prophesied by the eighth Khamtrul, Kelzang Denjued Nima Rinpoche, in 1975, driven by a vision to benefit all sentient beings. Beyond its spiritual purpose, the Lhakhang also serves a practical role in addressing the shortage of choeps, or monks, in Sarpang. By promoting the dharma and providing a sanctuary for religious practice, the Lhakhang not only preserves Bhutanese cultural heritage but also nurtures a supportive environment for spiritual growth and community cohesion. Its location and architectural design reflect a deep reverence for tradition and a commitment to fostering religious education and practice among both residents and visitors alike.
