This monastery, situated among the sacred sites of Guru Padmasambhava, primarily upholds the Nyingma School of Vajrayana Buddhism. Within the Nyingma tradition, the monastery focuses on the Longchen Nyingthik, the Heart Essence of the Great Expanse, a cycle of teachings revealed by the Omniscient Jigme Lingpa, along with various other Nyingma treasure teachings.

During the 9th century, Tibetan Prince Tsangma, a great Dzogchen practitioner and former monk, settled in this region of Bhutan after coming into exile. His descendants became the rulers of this eastern region, fostering the establishment of Buddha Dharma.

For several centuries, a significant trail route connected central Bhutan to the Trashi Yangtse District of Eastern Bhutan, extending to Tawang District in India and Tsona District in Tibet. This route also extended from North Trashi Yangtse District to Assam in India. Historical accounts indicate that several masters and treasure revealers such as Guru Chökyi Wangchuk, Sherab Mebar, Thangtong Gyalpo, Ratna Lingpa, Pema Lingpa, and Lhatsun Namkha Jigme traveled this route. Their journeys from Eastern Bhutan to Tibet and Assam in India blessed this area and fostered the flourishing of Buddha Dharma in general, and particularly Guru Rinpoche’s treasure teachings and the Dzogchen lineage in Eastern Bhutan.

Omniscient Longchenpa, a pioneer of the Dzogchen lineage in Tibet during the 14th century, visited many parts of Bhutan and founded numerous monasteries during his time. These monasteries later became known as the Eight Abodes of Longchenpa. His spiritual legacies and aspirations were crucial in ensuring the flourishing of the Dzogchen lineage of the Earlier Longchen Nyingtik in Eastern Bhutan as well.

In the autobiography of the Omniscient Jigme Lingpa, it is recorded that he visited Tsona, the bordering district of Tibet, Bhutan, and India, and Pangchen-nang in Mon Tawang District, India, which is situated behind a couple of mountains from this Long-nying Chöling Monastery. Many people from the Trashi Yangtse Valley received his blessings and teachings during that time. Although one of his students invited him to consecrate a new monastery, his busy schedule prevented him from traveling. Instead, he sent his prayers and blessings along with many blessed objects such as statues, stupas, and relics.

This auspicious event seems to have manifested Jigme Lingpa’s prayers in the region. For over a century, many Nyingtik lineage Lamas have visited and blessed this monastery and surrounding areas. From the first abbot, Ven. Yogi Lama Pema Drakpa, to the current abbot, Ven. Lama Norbu Wangdi, and Ven. Khenpo Namchak Dorji, the lineage has been meticulously maintained through study, contemplation, and meditation. Additionally, this monastery has served as a center for various Dharma activities, including the transmission of general Buddhist teachings, sacred Vajrayana empowerments, transmissions, and teachings. It also provides spiritual advice to the general public around the monastery, various ritual services for the living, and guiding prayers and rituals for the deceased.
