The root cause of wrongdoing is ignorance, and we must
therefore hold fast to the tools of perception and knowledge. Good character
must be taught. Light must be spread afar, so that, in the school of humanity,
all may acquire the heavenly characteristics of the spirit, and see for
themselves beyond any doubt that there is no fiercer hell, no more fiery abyss,
than to possess a character that is evil and unsound; no more darksome pit nor
loathsome torment than to show forth qualities which deserve to be condemned.
-‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha’)
