Frank Herbert said this quote

Three quick breaths triggered the responses: he fell into the floating awareness... focusing the consciousness... aortal dilation... avoiding the unfocused mechanism of consciousness... to be conscious by choice... blood enriched and swift-flooding the overload regions... one does not obtain food-safety freedom by instinct alone... animal consciousness does not extend beyond the given moment nor into the idea that its victims may become extinct... the animal destroys and does not produce... animal pleasures remain close to sensation levels and avoid the perceptual... the human requires a background grid through which to see his universe... focused consciousness by choice, this forms your grid... bodily integrity follows nerve-blood flow according to the deepest awareness of cell needs... all things/cells/beings are impermanent... strive for flow-permanence within...
