The wisdom of the appearance of the spirit in the body is this: the human spirit is a Divine Trust, and it must traverse all conditions, for its passage and movement through the conditions of existence will be the means of its acquiring perfections.
Abdu'l-BaháThe diversity in the human family should be the cause of love and harmony, as it is in music where many different notes blend together in the making of a perfect chord.
Abdu'l-BaháThe reality of man is his thought, not his material body. The thought force and the animal force are partners. Although man is part of the animal creation, he possesses a power of thought superior to all other created beings.
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-Bahá
