How do we know that we are getting closer to the persepctive of the right brain?
In paleontology, there is something called a search image. The untrained eye cannot easily identify fossils amidst the landscape. After some time, however, the eye begins to develop a search image, so that it can readily pick out fossils.
It might be useful to have something similar for venturing into right brain thinking. But the search image here is not so much a visual image, but a feeling.
For instance, feelings of synchronicity, and things happening that seem to defy logic.
Feelings of wonder, awe and magic.
These are valuable clues that we are entering the world of the right brain.
