The 6 Things Uniting in Harmony to be
Remembered:

The Blessed Buddha once said:
These six things are to be remembered in order to Unite any Community in
Harmony:
Which six?
1: Friendly
Behaviour (metta-kaya-kamma=friendly
bodily action) both in public & in private.
2: Friendly Speech (metta-vaci-kamma=friendly
verbal action) both in public & in private.
3: Friendly
Thought (metta-mano-kamma=friendly
mental action) both in public & in private.
4: Sharing
of Gains (sadharana-bhogi=common
wealth)
even down to any single lump of food.
5: Moral
Harmony (sila-samannagato=uniform
morality): All respect the same ethical rules.
6: Harmony
in Views (ditthi-samannagato=uniform
attitude): All share same general views.
These 6
things are to be considered and remembered both for individual & social Harmony...
