If love and agreement are manifest in a single family, that family will advance, become illumined and spiritual.
Abdu'l-BaháThe most important principle of divine philosophy is the oneness of the world of humanity, the unity of mankind, the bond conjoining East and West, the tie of love which blends human hearts.
Abdu'l-BaháLove ye all religions and all races with a love that is true and sincere and show that love through deeds.
Abdu'l-BaháThe 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-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
