The Buddha's Words on Loving Kindness

This is what should be done
By one who is skilled in goodness
And who knows the path 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 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
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
