There are many people who are curious about oracles in Tibetan Buddhism. I'm particularly interested so I'd like to start the thread about oracles and welcome everybody to share their information here.
The emphasis on oracles in Tibetan Buddhism is often confused with shamanism, but oracles and shamans are quite different.
An oracle is a spirit who speaks through a medium. It is channeling. Shamans, found in Siberia, Turkey, Africa, etc., are people who enter a trance in which they go to different realms and speak to various spirits, usually the spirits of ancestors. The spirits give them answers to various questions. When the shamans come out of trance, they deliver the message from the ancestors.
In contrast, a medium usually has no memory whatsoever of what the oracle said through him or her. Oracles became associated with protectors. The Nechung oracle is also the protector called Nechung.
A trace of shamanism, however, is reflected in a division of things as being on, above and below the earth, which is prevalent in Bon material and then came into Buddhism.
Buddha taught a tremendous amount on many topics. Wherever Buddhism went in Asia, people emphasized elements that resonated with their culture. There is mention of pure lands in Indian Buddhism but it was not emphasized.
The Chinese, who had the Daoist (Taoist) idea of going to the Western land of the immortals, put tremendous emphasis on the pure lands and expanded it tremendously. Thus, we get pure land Buddhism. It is one of the most significant Chinese Buddhist schools.
Likewise, within Indian Buddhism, we do find discussion of protectors, of various spirits, offering pujas and so on, but the Tibetans expanded these elements tremendously because it was in their culture.
