Step-by-step explanation:
A person being treated by a shaman would most likely be undergoing c) Shamanic Healing. Shamanic healing is a practice that often involves entering an altered state of consciousness to engage with the supernatural realm. This can be achieved through various means such as dreams, hallucinogenic drugs, rhythmic music, or dance. Shamans work with clients to address specific needs by making direct contact with deities or supernatural forces. Shamanism is an integral part of many indigenous cultures and is considered a form of healing and prophecy. It's also acknowledged within some of the world's dominant religions, such as Christianity and Islam, in practices like the laying on of hands or the whirling dances of Sufis.
Moreover, shamanism operates within a religious context, as it aligns with anthropological definitions of religion, involving shared beliefs and practices related to the natural and supernatural worlds. The role of the shaman varies across cultures, but it's commonly a part-time calling where individuals are drawn into practice through a perceived calling and are trained in necessary skills and rituals.
