Dhammapada · 7.7

Santaṃ tassa manaṃ hoti, santā vācā ca kamma ca;Sammadaññā vimuttassa, upasantassa tādino.

Santam tassa manam hoti, santa vaca ca kamma ca; Sammadanna vimuttassa, upasantassa tadino.

Tranquil is his mind, tranquil his speech, tranquil his action — one rightly knowing, fully released, at peace.
