In creation there is no evil; all is good. Certain qualities and natures innate in some men and apparently blameworthy are not so in reality. For example, form the beginning of his life you can see in a nursing child the signs of desire, of anger, and of temper. Then, it may be said, good and evil are innate in the reality of man, and this is contrary to the pure goodness of nature and creation. The answer to this is that desire, which is to ask for something more, is a praiseworthy quality provided that it is used suitably. So, if a man has desire to acquire science and knowledge, or to become compassionate, generous and just, it is most praiseworthy. If he exercises his anger and wrath against the bloodthirsty tyrants who are like ferocious beasts, it is very praiseworthy; but if he does not use these qualities in a right way, they are blameworthy... (195:1)
...It is the same with all the natural qualities of man.. if they be used.. in an unlawful way, they become blameworthy. Therefore it is clear that creation is purely good." ('Abdul-Baha) (195:2)
"..Error is lack of guidance; darkness is absence of light; ignorance is lack of knowledge; falsehood is lack of truthfulness; blindness is lack of sight; and deafness is lack of hearing. Therefore, error, blindness, deafness and ignorance are nonexistent things..
