I would say about individuals, A Individual dies when they cease to to be surprised. I am surprised every morning when I see the sunshine again. When I see an act of evil I don't accomodate, I don't accomodate myself to the violence that goes on everywhere. I am still so surprised! That is why I am against it. We must learn to be surprised.
Abraham Joshua HeschelNormal consciousness is a state of stupor, in which the sensibility to the wholly real and responsiveness to the stimuli of the spirit are reduced. The mystics, knowing that man is involved in a hidden history of the cosmos, endeavor to awake from the drowsiness and apathy and to regain the state of wakefulness for their enchanted souls.
