Richard Price borrowed from his novel Clockers, updating some of the jargon (crackheads and dealers from 1992 replaced by hoppers and hustlers in 2002) to write this closing scene from an episode of HBO's The Wire. Series creator David Simon often asked him to cannabilize from his book which inspired the show.
This is what should be done
By one who is skilled in goodness,
And who knows the path of peace:
... Wishing: In gladness and in safety,
May all beings be at ease.
Whatever living beings there may be;
Whether they are weak or strong, omitting none,
The great or the mighty,
medium, short 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 none deceive another,
Or despise any being in any state.
Let none through anger or ill-will
Wish harm upon another.
Even as a mother protects with her life
Her child, her only child,
So with a boundless heart
Should one 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,
One should sustain this recollection.
This is said to be the sublime abiding....
~ Suttanipata 1.8
