A material evil done by a person does not return to the evildoer, but the evil feeling which was created by the sinful deed will fester in his soul and sooner or later make him suffer.
If in the morning a person wants to do evil unto others, evil will return to him by nightfall.
—INDIAN WISDOM
The evildoer harms himself first, before he harms others.
—SAINT AUGUSTINE
Every man becomes what he teaches others to be. Those who gain victory over themselves will gain victory over others. It is most difficult to achieve victory over oneself. Every man has power only over himself.
—DHAMMAPADA , a book of BUDDHIST WISDOM
There is no material goodness which can restore the soul after the damage done by the evil which you create.
