Shamanic Beliefs

There are many variations of shamanism throughout the world, but several common beliefs are shared by all forms of shamanism.

• Spirits exist and they play important roles both in individual lives and in human society.
• The shaman can communicate with the spirit world.
• Spirits can be benevolent or malevolent.
• The shaman can treat sickness caused by malevolent spirits.
• The shaman can employ trance inducing techniques to incite visionary ecstasy and go on vision quests.
• The shaman's spirit can leave the body to enter the supernatural world to search for answers.
• The shaman evokes animal images as spirit guides, omens, and message-bearers.
• The shaman can tell the future, scry, throw bones/runes, and perform other varied forms of divination

Shamanism is based on the premise that the visible world is pervaded by invisible forces or spirits which affect the lives of the living. Although the causes of disease lie in the spiritual realm, both spiritual and physical methods are used to heal. Commonly, a shaman "enters the body" of the patient to confront the spiritual infirmity and heals by banishing the infectious spirit.

Many shamans have expert knowledge of medicinal plants native to their area, and an herbal treatment is often prescribed. In many places shamans learn directly from the plants, harnessing their effects and healing properties, after obtaining permission from the indwelling or patron spirits. Before a spirit can be summoned it must teach the shaman its song. The use of totemic items such as rocks with special powers and an animating spirit is common.
Such practices are presumably very ancient. Plato wrote in his Phaedrus that the "first prophecies were the words of an oak", and that those who lived at that time found it rewarding enough to "listen to an oak or a stone, so long as it was telling the truth".
