Sangomas believe they are able to access advice and guidance from the ancestors for their patients through spirit possession by an ancestor, or mediumship, throwing bones, or by dream interpretation. In possession states, the sangoma works themself into a trance through drumming, dancing and chanting, and allows their ego to step aside for an ancestor to take possession of his or her body and communicate directly with the patient, or dancing fervently beyond their stated ability. The sangoma will provide specific information about the problems of the patient. Some sangomas speak to their patients through normal conversation, whilst others speak in tongues, or languages foreign to their patients, but all languages used by sangomas are indigenous Southern African languages depending on the specific ancestors being called upon. Not all sangomas follow the same rituals or beliefs.
