Yes and no - you know Venn diagrams?
^ That is just an example, they have circles and they overlap and in places, more than 2 come together.
For the sake of this explanation, your “circle” is your reality bubble, the sphere of things you can directly influence through thought alone.
When you begin shamanic work, the first “circle” you try to overlap is the World Tree, the axis mundi, a concept found commonly around the world in all peoples regardless of cultural norms, level of technological development, and IQ.
So you, your little “circle” so to speak of consciousness, begins structuring the World Tree and then that overlaps you onto the primal archetype.
In core shamanism trainings, the next act after the World Tree link is to retrive an animal spirit helper, a second “circle” of consciousness that opens you up to even more power, influence, and potential knowledge.
Then, they will usually partner you up with another person and you immediately begin learning to journey FOR that person, to help them in some way - this causes their “circle” to open up to you, as a force granting more health, life, etc., all things we are spiritually inclined to want as humans.
So you now have your little “circle” being not just “in my head” which is the default state of an average joe’s daydream, but connected to the primal axis mundi, secondly, being permitted to influence another human’s reality, and third, you’re linked to an animal spirit who represents (arguably) spiritual forces that are transcendent compared to everyday consciousness.
With time, your circle grows to encompass many different circles, some people the little reality bubble of other people you’ve helped, and other kinds of spirits.
So, all the things within someone’s “circle”/reality bubble are both personal, and also, accessible to be shared by people who have learened this method.
