Whatever foe may do to foe,
or haters those they hate
the ill-directed mind indeed
can do one greater harm.
Dhammapada Verse 42
Explanation: When one bandit see another, he attacks the second bandit. In the same way, one person sees someone he hates, he also does harm to the hated person. But what the badly deployed mind does to the possessor of that mind is far worse than what a bandit would do to another bandit or what one hater will do to another hater.
