“Better than a thousand hollow words, is one word that brings peace” is commonly found attributed to the Buddha. And it’s more or less genuine. Here’s Buddharakkhita’s translation of the same verse:
Better than a thousand useless words is one useful word, hearing which one attains peace.
Dhammapada, verse 100
This is from Thomas Byrom’s rendering of the Dhammapada, which is generally very inaccurate, although poetic. In this case he was reasonably close to the mark.
Less successful are Byrom’s “There is pleasure and there is bliss. Forgo the first to possess the second,” “Follow then the shining ones, the wise, the awakened, the loving, for they know how to work and forbear,” and “Meditate. Live purely. Be quiet. Do your work with mastery. Like the moon, come out from behind the clouds! Shine.”
