Yungdrung Bon is the pre-Buddhist spiritual tradition of Tibet.
In fact, it is the original Buddhist religion of Tibet and Tibetan
people originated from Zhang Zhung. Yungdrung Bon was taught by
Buddha Tonpa Sherab in Wol-mo Loong-Ring (Shambala). The Buddha's
history can be traced back to over 18,000 years. The Buddha was
born as prince, married and had family. During his life time,
he paid a visit to Tibet direct from Wol-mo Loong-ring via Gang
Wal-so Rawa (Mount Wal-so Ra-wa). During that visit, the Buddha
and his entourage found Tibet a barren land. He taught the indigenous
people some causal Bon (Gyu-yi Bon) aspect of teachings, such
as healing arts, prayer flag hoisting and medicinal plant fumigation
etc. He however, prophesied that his emanation will come to the
land and introduce resultant Bon (Dre-bui Bon) teachings.
Later, the first King of Tibet Nya-tri Tsed-po, particularly
his son Mutri Tsed-po the second King of Tibet, took the task
of importing Yungdrung Bon teaching from the neighbouring country
Zhang Zhung. According Yungdrung Bon sources, 108 Royal scholars
of Zhang Zhung were entrusted to translate Yungdrung Bon teaching
from Zhang Zhung language into Tibetan language. That is how Yungdrung
Bon was imported into Tibet by these kings.
Beginning from 8th century, Tibetans also imported Dharma from
India. Since then, Tibet had two major religious traditions; Yungdrung
Bon and Dharma. Yungdrung Bon has five sub-schools and Dharma
with five sub-schools under their umbrella respectively. Both
the traditions emphasise the generating of indiscriminate love
and compassion and have similar views on the path. However, there
are historical and geographical differences etc.
