In the world of existence the animal is a captive of nature. Its actions are according to the exigencies and requirements of nature. It has no consideration or consciousness of good and evil. It simply follows its natural instinct and inclination. The Prophets of God have come to show man the way of righteousness in order that he may not follow his own natural impulse but govern his action by the light of Their precept and example. According to Their teachings he should do that which is found to be praiseworthy by the standard of reason and judgment of intellect, even though it be opposed to his natural human inclination; and he should not do that which is found to be unworthy by that same standard, even though it be in the direction of his natural impulse and desire. Therefore, man must follow and manifest the attributes of the Merciful.
- ‘Abdu’l-Baha (Excerpt from a talk given on 21 April 1912 in Washington D.C.; ‘The Promulgation of Universal Peace’)
