Close investigation will show that the primary cause of oppression and injustice, of unrighteousness, irregularity and disorder, is the people's lack of religious faith and the fact that they are uneducated.
Abdu'l-BaháThe pure heart is one that is entirely cut away from self. To be selfless is to be pure.
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-BaháLet us have love and more love; a love that melts all opposition, a love that conquers all foes, a love that sweeps away all barriers, a love that aboundeth in charity, a large-heartedness, tolerance, forgiveness and noble striving, a love that triumphs over all obstacles.
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
