““Everything we feel and do is somehow oriented "lifeward," and the least deviation away from this direction toward something beyond is difficult or alarming. This is true even of the simple act of walking: one lifts one's center of gravity, pushes it forward, and lets it drop again - and the slightest change, the merest hint of shrinking from this letting-oneself-drop-into-the-future, or even stopping to wonder at it - and one can no longer stand upright!””
