"The Characterization of Noble Speech:
Eliminating any false speech any Noble Friend dwells avoiding all lies,
a truth-speaker, one to be relied on, trustworthy, loyal, not a deceiver
of the world. Abstaining from malicious speech, he does not tell them there,
what he has heard about those here, or repeat here, what he heard there,
harming those there. Thus is he a reconciling diplomat stilling all quarrels.
The Noble Friend is rejoicing in peace, loving it, delighting in it, one who
defends peace. Abandoning all harsh and aggressive speech he refrains
from it. He speaks whatever is blameless and pleasing to the ear, agreeable,
touching the heart, elegant, gratifying and appealing to the many.
Discarding idle and empty chatter, he speaks at the right time & only about
what is correct, advantageous & to the point, of Dhamma and self-control.
He is a speaker, whose words are to be treasured and remembered, timely,
reasoned, well-defined, well-formulated, beneficial and leading to the goal...
This is Right and Noble Speech!"
