Venerable Kyabje Khentsen Ngawang Rabga Rinpoche was born in a remote village (Chyangmiteng) in Solukhumbu region of Nepal in 1960 AD, in an ordinary Sherpa family, to parents – Dorjee Sherpa (father) and Chiki Sherpa (mother). The family name given to him was Rinzi Sherpa.

From his very childhood Rinpoche was a simple, brave, honest, funny, friendly, farsighted person and had a strong desire to devote himself entirely to the spiritual life. At an early age Rinpoche joined Takgon Shedrup Thatling monastery which is about three hours walk from his birthplace. There he learned elementary Buddhist philosophy under the supervision of Ghesey Jhyangchup Tshultrim Rinpoche. During that period he also received the novice monastic vows (Gtashul) from His Holiness Kyabje Dzarong Trulshik Rinpoche.

Subsequently, in order to enhance his studies, Rinpoche migrated to Kathmandu, the capital city of Nepal. Then he got enrolled in Shechen Monastery for further Buddhist studies. At the age of 20 with the kindness of His Holiness Dilgo Khentsen Rinpoche and Rabjam Rinpoche, he acquired the training on ritual prayers according to the Mindroling tradition. He was then allocated as the prayer leader (Umze) for four years in Shechen monastery.

In the year 1989, Rinpoche entered Ngagyur Tholop Theguie Legshe Ling abbey in Sikkim to complete his higher Buddhist studies under the tutelage of his root guru, Rigzin Dorji Rinpoche, from whom he received all essential empowerments and instructions of the Nyingma tradition. During that period he was appointed as the chant master (Umze) for the very first Nyingma Monlam Chenmo (The World Peace Ceremony) for eleven years, organized by Darthang Rinpoche Kunga Gelek Yeshe Dorje, His Eminence Rigzin Dorjee Rinpoche and other high lamas which till date is held annually in Bodgaya, India. During the second annual Nyingma Monlam Chenmo he received the vow of fully fledged monk (Bikshu) from His Holiness Drubwang Padma Nurbu Rinpoche. Later in the year 1997, he completed his masters degree in Buddhist philosophy.

Henceforth, he started shouldering the responsibility of administration of Takgon Shedrup Tharling Monastery for successive eight years. On the other hand, overseeing the development and welfare of the monks and other beings, he founded Chyangmiteng Ogyen Chholing Monastery in that very same year at his birthplace.

While founding the monastery Rinpoche went through great hardships like, lacking financial support for the raw materials required to build the monastery, lacking cooperation from the villagers and so forth. However, bearing all hardships and weariness, Rinpoche himself engaged in manual work with the ordinary monks and the villagers. Even in the most searing sun, he worked diligently day after day, palms blistered and swollen. He did all the menial and basic tasks and went to perform rituals in the villages whenever requested, night or day. Thus, establishing the monastery Rinpoche restored the continuity of the Buddhadharma, enhanced the study of the profound teachings, and reintroduced the practice of rituals that had vanished in his region.

Hence, in the year 1999, he was entitled Khenpo by His Holiness Drubwang Pedma Nurbu Rinpoche in Nyingma Institute Taktse, Sikkim.

Later in the year 2006, the newly constructed monastery was consecrated by His Holiness Drubwang Pedma Norbu Rinpoche, meanwhile His Holiness bestowed empowerment on Nyingthik Cha-sum as well. Subsequently in the year 2011, Khen Rinpoche invited His Eminence Shechen Rabjam Rinpoche to give empowerment on Jyachon Pyaud-Thuk and Dorsem, the empowerment ceremony was attended by monks and laydevotees from all over Solukhumbu.

Accordingly, Rinpoche devoted considerable efforts to founding and sustaining different monasteries in Nepal- Takgon Shedrup Tharling Monastery at Taksindu, Chyangmiteng Ogyen Chholing monastery at Chyangmiteng, Ogyen Chholing Dharma Center at Taiwan, Dhinghur Ogyen Tashi Chholing Monastery at Dolkha, Nyamdroling Monastery at Kharikhola, Bhugyol Ogyen Chholing Monastery at Deusha, where the study and practice of the Buddhist tradition could be undertaken. One of his last activities was the establishment of The Eight Stupas which are associated with Buddha Shyakyamuni’s life. The main purpose for establishing these eight stupas were to prevent conflicts, disease, famine, and promote world peace and prosperity. His achievements in different fields seem more than enough to have filled an entire lifetime.

On 22nd December 2016, at the age of fifty-six, due to a sudden heart stroke Rinpoche passed away in Kathmandu at his abode. His cremation was attended by people from all over Solukhumbu including teachers and disciples from around the globe.

To date, there are about seventy monks present and engaged in studies in Ogyen Chholing Monastery. Food, clothing, accommodation and education are provided free of cost. So far, seven monks have graduated and became lecturers and are benefiting beings by rendering unwavering service to the Ngagyur Ningma tradition, thanks to the generosity of Kyabje Khentsen Ngawang Rabga Rinpoche.
Thus, the virtuous work he carried out simply cannot be imagined by ordinary beings. In this way, Rinpoche accomplished infinite service for the propagation of the Buddha Dharma as a whole and Nyingma Tradition in particular. Hence, Khentsen Ngawang Rabga Rinpoche’s efforts for the doctrine and sentient beings are immeasurable and are equal to only to the limits of space.
