The Last Chance to Become Enlightened
by Friends of Godwin
One other benefit of loving-kindness that is mentioned is that you can die with complete awareness. Why is dying consciously so important? One reason is that it is the last chance you have to become enlightened. So if you have missed it during your life, it is the last chance when you are dying.
So you can live peacefully, you can sleep peacefully, and you can die peacefully if you practice loving-kindness.
