The mind can go either direction under stress—toward positive or toward negative: on or off. Think of it as a spectrum whose extremes are unconsciousness at the negative end and hyperconsciousness at the positive end. The way the mind will lean under stress is strongly influenced by training.
Frank HerbertThe future remains uncertain and so it should, for it is the canvas upon which we paint our desires. Thus always the human condition faces a beautifully empty canvas. We possess only this moment in which to dedicate ourselves continuously to the sacred presence which we share and create.
