A man may be a Bah' in name only. If he is a Bah' in reality, his deeds and actions will be decisive proofs of it. What are the requirements? Love for mankind, sincerity toward all, reflecting the oneness of the world of humanity, philanthropy, becoming enkindled with the fire of the love of God, attainment to the knowledge of God and that which is conducive to human welfare.
Abdu'l-BaháThe mind and spirit of man advance when he is tried by suffering. ... so suffering and tribulation free man from the petty affairs of this worldly life until he arrives at a state of complete detachment.
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
