This is what should be done
by all who are skilled in goodness,
and who know the path of peace:
Let us be able and upright,
straightforward and gentle in speech,
humble and not conceited,
contented and easily satisfied,
unburdened with duties, and frugal in our ways.
Peaceful and calm, and wise and skillful,
not proud or demanding in nature,
let us not do the slightest thing
that the wise would later reprove.
In gladness and in safety,
let us wish that all beings be at ease.
Whatever living beings there may be;
whether they are weak or strong, omitting none
—the great or the mighty, big, middling, or small,
the seen and the unseen, those living near and far away,
those born and to-be-born—
may all beings be at ease!
Let us not deceive another,
or despise any being in any state.
Let us not through anger or ill-will
wish harm upon another.
Even as a mother protects with her own life
her child, her only child,
so with a boundless heart
should we cherish all living beings;
radiating kindness over the entire world:
spreading upwards to the skies,
and downwards to the depths;
outwards and unbounded,
freed from hatred and ill-will.
Whether standing or walking, seated or lying down
free from drowsiness,
we will sustain this recollection.
This is the sublime abiding.
By not holding to fixed views,
the pure hearted, having clarity of vision,
being freed from all sense desires,
is not born again into suffering.
—Buddha Shakyamuni, Maitri Sutra
