Shamanism is a spiritual practice in cultures around the world from ancient times to the present day. First and foremost, shamans' practices are practical and adaptable. These practices coexist over millennia with varying cultures, systems of government, and organized religious practices.
Many formalized religions, from Buddhism to Christianity, came from ancient shamanic roots and still bear the shamanic threads of deep connection to the divine in all things. But shamanism itself is not a formalized system of beliefs or an ideology. Rather, it is a group of activities and experiences shared by shamans in cultures around the world. These practices are adaptable and coexist with different cultures, systems of government, and organized religious practices.
Shamanism is based on the belief that a person can connect to the spirit world by engaging in an ecstatic trance. This process transcends the traditional ideal of reality and once a person is journeying, the shaman is able to draw incredible knowledge and healing power from within the depths of their being. There are three realms, or levels of inner consciousness, the Upper, Middle and Lower Worlds. These inner realms were within us since creation and we are not responsible for their existence, however, Shamanism believes we discovered them. The realms are held together in an unconscious world and are part of the fabric of our psyche, leaving our acceptance of them up to our free will.
