The Metta Sutta Ratnaprabha's translation

If you know what is truly good for you,
and understand the possibility of reaching the state,
Then this is how you need to live.
Start as a capable person who is upright, really upright,
Gently spoken, flexible and not conceited.

Then become contented and happy,
With few worries and an uncomplicated life.
Make sure your experience is calm and controlled
Be duly respectful, and don't hanker after families or groups

And avoid doing anything unworthy,
That wiser people would criticise.
Then meditate like this:
"May all beings become happy in their heart of hearts!"

And think of every living thing without exception:
The weak and the strong,
From the smallest to the largest,
Whether you see them or not.

Living beings nearby or far away,
Beings living now or yet to arise -
May all beings become happy in their heart of hearts!

May no one deceive or look down on anyone, anywhere,
For any reason,
Whether through feeling angry or through reacting to something else,
May no one want another to suffer.

As strongly as a mother, perhaps risking her life,
Cherishes her child, her only child,
Develop an unlimited heart for all beings.

Develop an unlimited heart of friendliness for the entirte universe,
Sending metta above, below and all around,
Beyond all narrowness, beyond all rivalry,
Beyond all hatred.

Whether you are staying in one place,
Or travelling, sitting down, or in bed,
In all your waking hours, rest in this mindfulness,
Which they say is like living in heaven, right here and now!

In this way, you will come to let go of views,
Be spontaneously ethical and have perfect Insight.
And leaving behind craving for sense pleasures,
From the round of rebirth you'll finally be completely free!
