I have continued to do the meditation that I described in my last post, hoping to contact my spirit guide again. I have had some mixed success. The central room that my meditation takes me to has many hallways leading off of it. I have met my spirit guide again and we have walked down one of the hallways together. He does not speak and all the doors are closed. I feel only curious, but we don't open any of the doors.
My spirit guide now appears to me either as the Native American man as he did originally or alternately as a movie version of Merlin.
After puzzling over this, I decided that the reason this meditation is not progressing is that my analytical mind is still interfering with my intuitive mind and perhaps scoffing at the whole thing. "If you want to talk to a wizard, HERE'S a wizard." And so I get the Merlin version.
I have spent my whole life being analytical and skeptical, I suppose that I should not hope to just tell that part of me to shut up and let my intuition speak and expect to have it work like a light switch.
I am finding this all fascinating, but I hope that I am not stuck in a loop.
