A trainee sangoma (or "ithwasane") trains formally under another sangoma for a period of anywhere between a number of months and many years. The training involves learning humility to the ancestors, purification through steaming, washing in the blood of sacrificed animals, and the use of muti, medicines with spiritual significance. The ithwasa may not see their families during training and must abstain from sexual contact and often live under harsh and strict conditions. This is part of the cleansing process to prepare the healer for a life's work of dedication to healing and the intense experiences of training tend to earn a deeply entrenched place in the sangoma's memory.
