Not by matted hair,
by clan, or by birth,
is one a brahmin.
Whoever has truth
& rectitude:
he is a pure one,
he, a brahmin.

What's the use of your matted hair,
you dullard?
What's the use of your deerskin cloak?
The tangle's inside you.
You comb the outside.

-Dhammapada, 26, translated by Thanissaro Bhikkhu.
