May All Beings Be at Ease

Metta Sutra

"This is what should be done
By one who is killed in goodness,
And who knows the paths of peace:
Let them be able and upright, 
Straightforward and gentle in speech.
Humble and not conceited,
Contented and easily satisfied. 
Unburdened with duties and frugal in their ways.
Peaceful and calm and wise and skillful,
Not proud and demanding in nature.
Let them not do the slightest thing
That the wise would later reprove.
Wishing: In gladness and 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 on 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,
Free 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,
By not holding to fixed views,
The pure hearted one, having clarity of vision,
Being freed from all sense desires,
Is not born again into this world."
