" There is another extreme to be wary of, I remind myself. Behind my desk I have a good library and a philosophy degree on the wall. I appreciate solid research and reasoned conclusions, but I get impatient when academicians limit the boundaries of truth within the five senses and the bicameral brain. At that point I put aside the book and step outside. There, with the warm colors of a sunset or the pastels of a rainbow, I breathe in the clear air and sense again my own Self. A bird chirps, a squirrel scurries up a tree. This divine Essence is greater than my body and utilizes more senses than my physical limitations. Scientists know that colors vibrate at a particular frequency, but there is much more going on; sentient beings delight in the pulsating rhythmic waves and lovers swoon in romantic locales. My own inner barometer senses a higher Order. A hawk or eagle catches my eye. It majestically circles above me, high in the blue sky, then it shoots off towards the west, where rain clouds gather. The sun is setting, light beams through, and a rainbow forms. Thank you Hawk. I get a thrill, my hair stands on end. Something else is here. Signs in the sky. Auspicious.
Yes. The mysteries are still here, and we are being called. "
