Step out onto the Planet
Draw a circle a hundred feet round.
Inside the circle are
300 things nobody understands,
and maybe nobody's ever seen.
How many can you find?
- Lew Welch

However deep your knowledge,
It is no more than a strand of hair
In the vastness of space;
However important appears
Your worldly experience,
It is but a drop of water in a deep ravine.
-Tokusan
