Shamanism is a combination of various beliefs and practices of the spirit world. Shamans act as messengers to and from the spirit world. They are able to acquire knowledge and understanding by being in the spiritual dimension and possessing travel guides in the form of spirits. It is through the spiritual dimension, that Shamanic practitioners are able to access and heal the spirit, which in turn can heal physical illness as well.
As much as Shamanism is a calling, you would need the guidance learning about and navigating through the spirit world by other Shamanic practitioners and teachers. LightSong School of Shamanic Studies and Energy Medicine is one of the leading providers of programs and courses focused on Shamanic practices. LightSong teachers will provide guidance on how to behave and work while in the spirit world in order to help yourself, others and society as a whole.
