Explorers in the high-altitude forests of North Sikkim have discovered a perfectly preserved 9th-century Buddhist Vihara. The rock-cut structure contains a central prayer hall adorned with rare Tantric murals that depict the syncretic transition between late Indian Buddhism and early Himalayan Vajrayana traditions.
The murals, preserved by the cave's unique microclimate, feature vibrant mineral pigments and Sanskrit inscriptions. Scholars believe the site served as a secluded retreat for scholars fleeing the political upheavals of the plains, making it a critical link in understanding the survival and spread of Indian Buddhist philosophy into the trans-Himalayan region.
