Illnesses which occur because of physical causes should be treated by doctors with medical remedies; those which are due to spiritual causes disappear through spiritual means. Thus an illness caused by affliction, fear, nervous impressions, will be healed more effectively by spiritual rather than physical treatment. Hence, both kinds of treatment should be followed; they are not contradictory.
Abdu'l-BaháLet them at all times concern themselves with doing a kindly thing for one of their fellows, offering to someone love, consideration, thoughtful help.
Abdu'l-BaháUntil the reality of equality between man and woman is fully established and attained, the highest social development of mankind is not possible.
Abdu'l-BaháTo oppose knowledge is ignorant, and he who detests knowledge and science is not a man, but rather an animal without intelligence. For knowledge is light, life, felicity, perfection, beauty and the means of approaching the Threshold of Unity. It is the honor and glory of the world of humanity, and the greatest bounty of God. Knowledge is identical with guidance, and ignorance is real error
Abdu'l-Bahá
