Dhammapada verses 96 and 97

96. Calm is his thought, calm his speech, and calm his deed, who, truly knowing, is wholly freed, perfectly tranquil and wise.

97. The man who is without blind faith, who knows the Uncreated, who has severed all links, destroyed all causes (for karma, good and evil), and thrown out all desires — he, truly, is the most excellent of men.
