The reign of Hlato Ri Nyentsen, the twenty-eighth king of Tibet (c.
500 CE), marked the first historic introduction of Buddhist scripture
into Tibet, though there was an oral tradition of Buddhism dating back
to the second century CE. The king had a dream in which a sacred text
fell from heaven. Since this text was not translated into Tibetan,
Buddhist teachings continued to spread slowly through Tibet.
Nyentsen's palace, Yumbu Lakang, was built in the second century near
Nedong, in central Tibet. It was named Yumbu (doe) for the shape of
the nearby Jormo Zhaxi Ceri Mountain and Lakang to denote a holy
palace.
