Shamans in indigenous cultures are spiritual healers who have learned through oral tradition how to channel their energy to alleviate ailments that effect the mind, body, spirit and soul. 

“Because it is not a organized religion as such, but rather a spiritual practice, shamanism cuts across all faiths and creeds, reaching deep levels of ancestral memory.  As a primal belief system, which precedes established religion, it has its own symbolism and cosmology, inhabited by beings, gods and totems who display similar characteristics although they appear in various forms, depending upon their places of origin.” 

– John Matthews, the Celtic Shaman
