Observe 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-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-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-BaháIf love and agreement are manifest in a single family, that family will advance, become illumined and spiritual.
Abdu'l-BaháTruthfulness is the foundation of all virtues of the world of humanity. Without truthfulness, progress and success in all the worlds of God are impossible for a soul. When this holy attribute is established in man, all the divine qualities will also become realized.
Abdu'l-Bahá
