A Peruvian shaman at an Ayahuasca Ceremony

The Shamanic Trance transports a shaman into the otherworld, allowing them to accompany the dead on their journey and to heal the sick.
The Prophetic trance has the reverse effect, letting the otherworld channel itself into this world through the shaman. This brought with it the power to speak as god, or to contact the dead.
The Mystical Trance blended this world and the other together and is marked by a great intuitive and emotional understanding of why and how both worlds work and the cosmology of the system as a whole.

The otherworld can be visualised as a sea of consciousness all around us. The ecstatic trance allows access to a transcendent portion of that sea where freer movement is possible. It is these transcendent states that shape the shaman, and perhaps communication of these states by an artist that reveals the shamanic nature of their art.
