Anxiety
When one approaches a long awaited destination it is common to become anxious in anticipation of it. One may have trekked all day with ease, but when the destination is neared fears and anxieties surface. Painfully, time takes twice as long.
Some have a power of mind that prevents such anxiety. They use mental tricks: such as not thinking of the destination at all, or imagining it as if in a dream, or even imagining there are still several days travel ahead. Whichever way, reality is put at a safe distance.
The wise are altogether different. They don't let false concepts of "time" and "distance", or "self" and "goal" arise. Wisdom cannot be troubled.
