It can be a good thing, or a bad thing; it can be used to heal wounds, or make them grow. Depending on your state of mind and subconscious, it can be hardly noticed, or be ever so tedious. It never ends. Hard to comprehend, right? Of course� that�s why it�s there.
The three most incomprehensible concepts are time, space (not necessary outer space), and death. You can�t ask because you can�t know. And you will never know. No one ever will.
In a perfect life, one would be able to live without the worries and barriers of those three things. But a perfect life does not exist, of course.
All you get to do is live and wonder, until you die.
