The world is incomprehensible.
We won't ever understand it;
we won't ever unravel its secrets.
Thus we must treat the world as it is:
a sheer mystery.
- Carlos Castaneda

Uncertainty that comes from knowledge
(knowing what you don't know)
is different from uncertainty coming from ignorance.
- Isaac Asimov

God is not what you imagine,
or what you think you understand.
If you understand you have failed.
- Saint Augustine

As soon as man does not take his existence for granted,
but beholds it as something
unfathomably mysterious, thought begins.
- Albert Schweitzer

Be thankful that life is a mystery.
There is so much we can never know.
Breathe deeply and relax into the not-knowing.
There is much that we do not have to know in order to live joyfully.
We Can Never Understand Our World, But We Can Still Enjoy It.
- Jonathan Lockwood Huie
