Eddie, you asked a question, above, on how one can test the parameters of the Mind. I posit that consciousness itself is the test and the tester. Intuition, a favorite pastime that women excel at, is the sensory systems throughout the body. By intuition, I mean that INSIGHT and REALIZATION are the tools of consciousness to render a few facts about the reality of conscious knowing. It is something that we humans are good at. Imagery, audible thoughts, every sensory application of the body and experiential responses are the process of "testing" the suppositions that move through our awareness.
I believe, clearly, that exotic means, as practiced by shamans, are the exponents of verification that informs us the same way that the searcher uses to pronounce the edification of the conscious experience of Being. How else do you propose to test Mind? With machines? Maybe. But personal and subjective means allow us to perceive much, if not yet all, considerations of Mind and Being. I can only suggest the means, not the actual results of such scrutiny. Subjective means "personal", and truly does go a long way into the "rabbit hole".
Remember: Ask, Seek, Knock. These are the prerequisites to knowing what we are, as Mind.
Mind and matter are eternally the same
