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.
The individual must be educated to such a high degree that he would rather have his throat cut than tell a lie, and would think it easier to be slashed with a sword or pierced with a spear than to utter calumny or be carried away by wrath.
Thus will be kindled the sense of human dignity and pride, to burn away the reapings of lustful appetites. Then will each one of God's beloved shine out as a bright moon with qualities of the spirit, and the relationship of each to the Sacred Threshold of his Lord will be not illusory but sound and real, will be as the very foundation of the building, not some embellishment on its facade. (‘Abdu'l-Baha, Selections from the Writings of ‘Abdu'l-Baha)
