The medicine wheel has many meanings in shamanistic traditions and one of them is being a signpost in the dreaming reality. Together with your power animals, it leads you towards totality. To clarify: in dreaming you learn to travel with your dream- or energy body from this reality to the boundless second reality to discover that you are the creator of your own reality. Shaman Vidar taught me about this medicine wheel ritual and you read more about this in the next excerpt from my book The Sorcerer’s Dream.
"In the late 1970's I had a vision of the Medicine Wheel, an ancient stone circle which has been used for thousands of years by Native people as a place for prayer, ceremony and self-understanding.... It sometimes makes me smile to think that there is such an air of mystery surrounding the old medicine wheels: How were they used? Why did they have a particular number of stones arranged in a certain way upon the ground? And so on."
"The mandala (Sanskrit for "circle") is a Hindu and Buddhist design used as an instrument of contemplation. Mandalas can enhance meditation by illustrating the microcosm (the self) within the macrocosm (the universe). The circular mandala has obvious parallels with the modern medicine wheel, and has the same purpose of reminding the viewer of the balance, harmony, and integral nature of existence. C. G. Jung called the mandala a symbol of the soul (Owen, 2002)."
