What reward should a good deed bring you? Only the joy you receive by performing it. And any other reward lessens the feeling of this joy.
He who does good to others makes the biggest gift to himself.
— Lucius Annaeus Seneca
A saint prayed to God in the following way: "0 God, please be kind to evil people as much as you are to kind people. Kind people already feel good, because they are kind."
— Muslih-Ud-Din Saadi
If you do good and ask for a reward, you weaken the force of your goodness.
— From the Book Of Divine Thoughts
Do not let your left hand know what your right hand is doing.
— Matthew 6:3
What a joy it is to do a good deed! And this joy is strongest if no one knows that you have done it.
