The one seeking enlightenment
brings his books with
him to Tibet.

He studies from the master

The master tells him to
travel far up the mountain
in the freezing snow

"Be sure and take your books!" the master reminds

The one seeking enlightenment
finds a small hut, not
even enclosed to protect
from the freezing wind

He sits and thinks
but the cold is getting colder

Then, he is enlightened!

He tears the pages from his books
one
by
one
And burns them to keep from dying
