time

Notice how time flies when you're happy. "Hey, it's evening!" And if you are very happy, then time not only "flies", but also stops. There isn't. You are in a dimension where there are no clocks. There is no tomorrow. Not yesterday either. There is no "now" either - because once you know that there is "now", you immediately start to fear that it will all pass.

What is durable is not what resists time, but what changes wisely with it.
