This is the world we live in. It is the physical reality of our five senses. It is the world that we describe through our chemistry and physics, the conscious mind and faith. In this reality, there is separateness: a beginning and an end; a cause and an effect.
Coined by Carlos Casteneda, Non-ordinary reality is the world of spirit. It is the world of dreams, spirits and intuition. It is where all things are conscious. It is the place of "no time" where the past, present and future all exist and are accessible. It is the place where thoughts, feelings and emotions create our physical reality and is the spirit mirror of our ordinary reality. In this place, all is connected and related. It is a place of symbolism. The Shaman "journeys" to non-ordinary reality to access the information contained therein. He then uses this data to help facilitate healing in ordinary reality.
Shamanism, specifically the shamanic journey, is used primarily for divination and healing. Shamans utilize the journeying techniques to study with their individual spirit teachers in non-ordinary reality. During the journey, the shaman can gain knowledge and insight from Spirit Guides as to what is necessary to restore spiritual power, and heal oneself, others, and the Planet.
