Learn well yourself this Law
That the Blessed One has taught;
Teach it to others in compassionate love
By the results of skillful acts performed.
Bar forever the roads to realms of woe

A 15th century, Sri Lankan poem beautifully exhorting the listener to the ethical life and to right view.

Listen to the poem sung in the original Sinhala on Archive.org.
