The Ven. Nedo Kuchung Rinpoche is the sixth Reincarnation in the supreme Nedo Kuchung lineage. The Fifth Nedo, Pema Lhundup, was the foremost disciple of the great scholar and siddha Karma Pema Chagme ( Ragha Akse). He was a great Lama, unequaled in kindness, and he was also an accompolished meditator having realized the highest stage of  Mahamudra and Maha Ati, and realizing their view and intentions. Not long after his death, his cousin, the supreme incarnation Dechen Nyingpo who was also from the tribe of Kham Nangchen, built the first Nedo Sanghag Chindu Dhargeling  Monastery in lower Gegyel in Kham, Eastern Tibet. There, the Karma kamtsang and the Nedo Kagyu tradition flourished under the supervision of the Monastery's Three Seat-holders: Dechen Nyingpo Rinpoche, Chod La Pema Dondrup Rinpoche, and Nedo Kuchung Rinpoche. The monastery had at one time more than 300 monks.

The present Nedo Kuchung Rinpoche was born on August 2, 1962 in Pema Thang, at the Himalaya. His father was Gandir and his mother was Yangchen. There were many wonderful signs during his birth.

In 1972, at the age of 10, His Holiness, the 16th Gyalwa Karmapa Rangjung Rigpe Dorje recognized him without any doubt that he was the incarnation of Shedrub Nyedun Chokyi Sengge, the previous Nedo Rinpoche, and gave him the name Karma Thinley Yongdu Kunchab Palzangpo. The same year, in Tashi Jong in Himachal Pradesh, His Holiness Dilgo Khyentse Rinpoche, the Crown Jewel in the Rime (non-sectarian movement), formally recognized him and offered him the robes and his title.

When he was 14 years old, he took the novice monk's vows (Gesuln) and was given the name Karma Tenpe Gyaltsen. When he was 18 years old, upon instruction from His Holiness 16th Gyalwa Karmapa, he went to Lhadak Monastery in Thubten Chokhor Ling on His Holiness 16th Gyalwa Karmapa's behalf. There he stayed for three years, taking care of the Monastery and its monks and giving teachings and initiations to the lay people in the area.

During his three years of stay in Lhadak Monastery, he has also received many valuable teachings and initiation from Ven. Tsurpu Dupon Dechen Rinpoche who was taking care of the monks in Lhadak. That was actually the reason that he went to Lhadak Monastery. He took the full ordination vows at the age of 21 also from His Holiness the 16th Gyalwa Karmapa.

Nedo Kuchung Rinpoche's main teachers were His Holiness the 16th Karmapa, His Holiness Dilgo Khyentse Rinpoche, Ven. Riwa Saljay Rinpoche, and Ven. Urgyen Tulku. He received from them many teachings on both the old and new traditions, reading transmission, empowerment, explanations, etc.

In 1982, at the age of 23, he went back to Rumtek Monastery to join the second batch of three-year retreat.  Under the guidance of the Ven. Boukar Rinpoche, the retreat master, he practiced the Tantras of Marpa's traditions, the six yoga’s of Naropa, and Mahamudra. He also received the ordinary and extraordinary initiations, oral transmission and Mahamudra, and Maha Ati's quintessential teachings thus gaining not only complete understanding but also realizing these teachings.

At the age of 25, coming out from his successful retreat, the Four Eminence enthroned him as the Vajra Master of Rumtek Monastery - a position he is holding until the present.

His present residence is Nedo Monastery in Kaiyathang East Sikkim, founded in 1996.
