There is, Oh Monks, a not-born, a not-become, a not-made, a not-compounded. Monks, if that unborn, not-become, not-made, not-compounded were not, there would be no escape from this here that is born, become, made and compounded.

If for just the time of a finger-snap a monk produces a thought of loving-kindness, develops it, gives attention to it, such a one is rightly called a monk. Not in vain does he meditate. He acts in accordance with the master's teaching, he follows his advice. How much more so if he cultivates it.
One should not kill a living being, nor cause it to be killed, nor should one incite another to kill. Do not injure any being, either strong or weak, in the world.
That which goeth up must needs come down; and that which is down must needs go up. But Brahma has ordained that the that that goeth up is seldom the same as the that that hath gone down.
