If we are wronged it hurts us not; if we wrong others, we do not suffer for it

Context

“But most men miscarry and never come to the true birth at all and some live but a very short time in a very little world and none are eternal. Still, the life we live beyond the grave is our truest life, and our happiest, for we pass it in the profoundest sleep as though we were children in our cradles. If we are wronged it hurts us not; if we wrong others, we do not suffer for it; and when we die, as even the Handels and Bellinis and Shakespeares sooner or later do, we die easily, know neither fear nor pain and live anew in the lives of those who have been begotten of our work and who have for the time come up in our room.” source
