Time has two aspects. There is the arrow, the running river, without which there is no change, no progress, or direction, or creation. And there is the circle or the cycle, without which there is chaos, meaningless succession of instants, a world without clocks or seasons or promises.
Ursula K. Le GuinTo see a candle's light, one must take it into a dark place. This is the same as to see the good and be grateful, one must compare and contrast it with something worse - not better!
Ursula K. Le GuinEven in merely reading a fairytale, we must let go our daylight convictions and trust ourselves to be guided by dark figures, in silence; and when we come back, it may be very hard to describe where we have been.
