Final answer:
Aboriginal shamans use methods like trance dancing, music, hallucinogenic drugs, and animal fats to achieve heightened spiritual consciousness and enter altered states for divination and healing.
Step-by-step explanation:
In order to achieve heightened spiritual consciousness, Aboriginal shamans use various methods, including trance dancing, rhythmic music, hallucinogenic drugs, exhaustion through dance, and sometimes animal fat from a "power animal" in their rituals. These practices allow them to enter altered states of consciousness where they can engage with the supernatural realm for purposes such as healing, divination, and locating wild animals. Specifically, the !Kung San use a medicine dance called n/um tchai to draw up spiritual forces for self-healing, while others may use herbal medicines or other ritualistic practices.
