We 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-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-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
