To 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-BaháLet them at all times concern themselves with doing a kindly thing for one of their fellows, offering to someone love, consideration, thoughtful help.
Abdu'l-BaháTo promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
Abdu'l-BaháIf a man has ten good qualities and one bad one, to look at the ten and forget the one, and if a man has ten bad qualities and one good one, to look at the one and forget the ten.
Abdu'l-BaháTo attain eternal happiness one must suffer. He who has reached the state of self-sacrifice has true joy. Temporal joy will vanish.
Abdu'l-Bahá
