unknown than your belief system allows, then by all means travel on the imagination. What you will find is that you are not making it up at all. The spirits are alive and well, existing in other realities that you probably cannot see with your physical eyes, but are real just the same. The imagination provides the avenue to get there.
So use your imagination, develop it, and allow it to expand, create, grow, and become. Open the door and get out of the box that society has placed around you. You will find that the shamanic journey and your spirit helpers continually provide you with ideas, information, possibilities, and potentials for your own growth and development.
