events), bouts of insanity (including those induced by psychological trauma from a past event), and strange visions or dreams. These are regarded as encounters with the spirits, where the soul of the person is said to be journeying to the spirit world. In cases like this, it is said that a spirit chose the person, rather than the other way around. After being chosen, shamans go through an initiation rite. These rites are meant to gain or transfer the patronage of a spirit. Among Visayans, this ritual is known as the tupad or tupadan. In cases of people with "shamanic illness", these initiation rites are regarded as the cure, where the initiate regains health or sanity by conceding to the wishes of the spirits and "answering the call". When volunteered rather than volunteering, their relatives are usually required to pay a large fee to the senior shaman for the training. Initiation rites can range from simply inducing a trance through herbs or alcohol, to inducing personal crises through physical or psychological hardship. Extreme examples of initiation rites include getting buried alive or being immersed in water overnight. After initiation, the apprentices are then trained in the details of their role. This training includes learning about the rituals, the chants and songs, the sacrifices appropriate for each spirit, oral histories, herbs and healing practices, and magic spells, among others. They usually assist the senior shaman during ceremonies until their training is complete, which can take months to years. Each shaman can have one or more such apprentices, at varying ranks or specializations. Spirit guides The shaman's power to communicate with the spirit world is derived from their spirit companions that guide them and intercede for them. These spirits are usually referred to in euphemistic terms like abyan ("friend"), alagad or bantay ("guardian"), or gabay ("guide"), among other terms. Shamans have at least one abyan, with more powerful shamans having many. Certain individuals like powerful leaders or warriors (especially those with shaman relatives) are also believed to have their own abyan that give them magical powers. Abyan are also believed to guide, teach, and inspire skilled artists and craftsmen in the community. Abyan spirits can be ancestor spirits, but they are more commonly non-human spirits. Shamans either had spirit companions from birth, drew their attention during the "shamanic illness", or gained their allegiance during initiation into shamanism. Spirits are believed to be
