Metta Sutta

Let them not do the slightest thing that the wise would later reprove.
They should wish:

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!

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.
