Margaret, I find the information you posted fascinating. I've used Delta entrainment over the years and it **definitely** increased my intuitive abilities. This is a gross understatement and many of the experiences I've had seemed totally normal to me at the time, yet were totally paranormal in any kind of normal context.
The data you posted about earliest man having predominantly a Delta state makes sense to me, but I'm just wondering if you can point me to a reference where this information comes from. Without actually hooking up an ancient human to an EEG machine (which is obviously impossible), how can we know what early man's brainwaves were?
It shocks me that some of my most peaceful, clear, and transcendental states of being may have been when my brainwaves became those of our earliest ancestors. Whatever happened to evolution? Aren't things supposed to get better, not worse? Is regression to early human's brainwaves actually a progression??
