Harm Not An Arahat

One should not strike a holy man,nor should a holy man, when struck, give way to anger.Shame on him who strikes a holy man,and more shame on him who gives way to anger.– Dhammapada XXVI. Brahmanavagga: The Holy Man :: Verse 389

An Arahat Does Not Retaliate

Nothing is better for a holy man than when he holds his mind back from what is endearing.To the extent the intent to harm wears away,to that extent does suffering subside.– Dhammapada XXVI. Brahmanavagga: The Holy Man :: Verse 390
