DEVELOP a state of mind like the earth, Rahula. For on the earth people throw clean and unclean things, dung and urine, spittle, pus, blood, and the earth is not troubled or repelled or disgusted. And as you grow like the earth no contacts with pleasant or unpleasant will lay hold of your mind or stick to it

In this world
Hate never yet dispelled hate.
Only love dispels hate.
This is the law,
Ancient and inexhaustible.
You too shall pass away.
Knowing this, how can you quarrel?
from the DHAMMAPADA,
translated by Thomas Byrom
