Do not deceive, do not despise each other anywhere. Do not be angry nor bear secret resentments; for as a mother will risk her life and watches over her child, so boundless be your love to all, so tender, kind and mild.

Cherish good will right and left, early and late, and without hindrance, without stint, be free of hate and envy, while standing and walking and sitting down, what ever you have in mind, the rule of life that is always best is to be loving-kind.

-- The Buddhist Scriptures, The Buddha’s Sermon at Rajagaha, Verses 19-22
