Why were guardian spirits important to shamans?

In the context of shamanism, guardian spirits are essential because they provide the supernatural assistance and authority required for a shaman to perform their professional duties. Shamans are believed to be aided by an active spirit-being or a group of spirits, which enables them to communicate directly with the transcendent world.1

These spirits are vital for several reasons:

• Communication and Trance: Shamans rely on spirits to facilitate their entry into the spirit realm, either by allowing their own soul to leave their body or by acting as a mouthpiece for the spirit-being.1
• Healing and Divination: Because illness is often attributed to the actions of spirits—such as soul loss or spirit possession—shamans require the power of their guardian spirits to appease, drive out, or negotiate with these entities to effect a cure.2
• Professional Authority: The shaman’s ability to foresee distant events, locate lost animals, and act as a psychopomp for the deceased is derived from their direct connection to the spirit world.2
• Protection: In mystical combat, shamans may engage in battles with other spirits or rival shamans to protect their community from harm.3
