Divine madness, also known as theia mania and crazy wisdom, refers to unconventional, outrageous, unexpected, or unpredictable behavior linked to religious or spiritual pursuits. Examples of divine madness can be found in Buddhism, Christianity, Hellenism, Hinduism, Islam, Judaism and Shamanism.

Shamanism or samanism is a religious practice that involves a practitioner interacting with the spirit world through altered states of consciousness, such as trance. The goal of this is usually to direct spirits or spiritual energies into the physical world for the purpose of healing, divination, or to aid human beings in some other way.
