Strive for this

 Let your love flow outward through the universe,
To its height, its depth, its broad extent,
A limitless love, without hatred or enmity.
Then, as you stand or walk,
Sit or lie down,
As long as you are awake,
Strive for this with a one-pointed mind;
Your life will bring heaven to earth.

               Gautama Buddha, Sutta Nipata
