Nyamme Sherab Gyaltsen received complete transmission of empowerment (wang), oral transmission (lung), and oral instruction (tri) of the three main streams of Bön teaching: Dho, Ngag, and Dzogchen. He received fully-ordained monks’ vows at the age of 31 and entered into the great center of learning of Bön – the Yeru Monastery in Tsang province. By participating in many other renowned Buddhist institutions and monasteries, he became very well known in Tibet and was recognized as a great wisdom scholar. During his stay at the Yeru monastery, he took charge of one of the schools. He also became a tutor of two royal sons of Dru lineages and was enthroned as the successor of Kunga Wangden, the famous master of the Dru lineages. Through his work he preserved and spread the outer, inner and secret teachings of Bön. From that time forward, every monastery has followed the exact same clear knowledge of the ancient system of monastic laws brought to life by Nyamme Sherab Gyaltsen.
In 1405, he founded the original Menri Monastery known as Tashi Menri Ling in the mountains. Bön protectors directed him as to where exactly he should build Menri Monastery. With support from them and miraculous powers, he built the whole structure of Menri Temple including the monks’ living quarters. He decided to preserve there the traditions and teaching system of the destroyed Yeru Wensakha monastery. Tashi Menri Ling Monastery soon became the mother monastery of Bön.
Nyamme Sherab Gyaltsen became the crowning ornament of Bön for his mastery of text, systems and rules; he came to be considered as the second Buddha. There really are no texts from these three sections of Dho, Ngag and Dzogchen that he did not teach or write about in all of the three transmission lineages of Bön. He passed away at the age of 60, leaving behind many great scholars and practitioners.
