Dhamme ca ye ariyapavedite ratā
anuttarā te vacasā, manasā kammunā ca.
Te santisoraccasamādhisaṇṭhitā,
sutassa paññāya ca sāramajjhagū.

Those who are devoted to the Dhamma made known by the Noble Ones
are unsurpassed in speech, thought and action.
They are established in peace, gentleness and concentration,
and have reached the essence of learning and wisdom.
