What profit is there in agreeing that universal friendship is good, and talking of the solidarity of the human race as a grand ideal? Unless these thoughts are translated into the world of action, they are useless. The wrong in the world continues to exist just because people only talk of their ideals, and do not strive to put them into practice. If actions took the place of words, the world's misery would very soon be changed into comfort.
Abdu'l-BaháTo promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
Abdu'l-BaháClose investigation will show that the primary cause of oppression and injustice, of unrighteousness, irregularity and disorder, is the people's lack of religious faith and the fact that they are uneducated.
Abdu'l-BaháWe should all visit the sick. When they are in sorrow and suffering, it is a real help and benefit to have a friend come. Happiness is a great healer to those who are ill....This has a greater effect than the remedy itself. You must always have this thought of love and affection when you visit the ailing and afflicted.
Abdu'l-BaháIllnesses 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-Bahá
