Loving Kindness : Metta Sutra

She or he who wants to attain peace should practice being upright, humble, and capable of using loving speech. He or she will know how to live simply and happily, with senses calmed, without being covetous, or carried away by the emotions of others.

And this is what she or he contemplates:

May everyone be happy and safe, and may their hearts be filled with joy. May all living beings live in security and peace—beings who are frail or strong, tall or short, big or small, visible or not visible, near or far away, already born, or yet to be born.

May all of them dwell in perfect tranquillity.

Let no one do harm to anyone. Let no one put the life of anyone in danger. Let no one, out of anger or ill will, wish anyone any harm.

Just as a mother loves and protects her only child at the risk of her own life, let us cultivate boundless love to offer to all beings in the entire cosmos. Let our boundless love pervade the whole universe, above, below and across. Our love will know no obstacles, our heart will be absolutely free from hatred and enmity. Whether standing or walking, sitting or lying, as long as we are awake, let us maintain this mindfulness of love in our heart.

This is the noblest way of living.
