She stands between worlds

Deciphering Heaven and Earth by Caroline Robinson

What is a shaman? Classically a shaman was a messenger between the human world and the spirit world/underworld but this can also be understood as the unconscious, our own individual unconscious and also the collective unconscious that we share as humans. 

To access these places and it's knowledge, she may use altered states of consciousness (trance states), dance, music and/or herbs and tonics.
 

She is a messenger between the human world and the spirit world said to treat ailments/illness by mending the soul.

Alleviating traumas affecting the soul or spirit restores the physical body and brings one back to balance and wholeness.
