What these men were describing, I realized, was a pattern of path
breaking common to all living things: One caterpillar finds a new leaf,
and ten more follow its trail. By the time the eleventh arrives, the leaf
has been chewed down to its skeleton, and so the eleventh caterpillar grows hungry and sets off in a new direction. The same principle
applies to foraging ants and grazing herds, to fashion trends and stock markets, to traffic-clogged roads and eroded hiking paths.
Robert Moor, On Trails
The soul would have no rainbow if the eyes had no tears.
Indian proverb
