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-BaháWhat 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-BaháBahá'í marriage is union and cordial affection between the two parties. They must, however, exercise the utmost care and become acquainted with each other's character. This eternal bond should be made secure by a firm covenant, and the intention should be to foster harmony, fellowship and unity and to attain everlasting life.
Abdu'l-BaháObserve that the body of man is confined to a small place; it covers only two spans of earth. But the spirit and mind of man travel to all countries and regions - even through the limitless space of the heavens - surround all that exists, and make discoveries in the exalted spheres and infinite distances. This is because the spirit has no place; it is placeless; and for the spirit the earth and the heaven are as one since it makes discoveries in both.
Abdu'l-Bahá
