The one, more often chanted by Theravadin monks, is also referred to as Karaṇīyamettā Sutta after the opening word, Karaṇīyam, "(This is what) should be done.
It is ten verses in length and it extols both the virtuous qualities and the meditative development of mettā (Pali), traditionally translated as "loving kindness"[2] or "friendliness".
The other, also chanted by Theravadin Buddhist monks at times, extols the benefits of the practice of mettā (Pali) and it is found in the Anguttara Nikaya (AN 11.15).
These include such qualities as being non-deceptive (uju), sincere (suju), easy to correct (suvaco), gentle (mudu) and without arrogance (anatimānī).
It has been reported that Buddhist monks chanted the Mettā Sutta as part of their demonstration in September and October 2007 against the military in Burma.
