An humble man without learning, but filled with the Holy Spirit, is more powerful than the most nobly-born profound scholar without that inspiration. He who is educated by the Divine Spirit can, in his time, lead others to receive the same Spirit.
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-BaháAnd now one of the greatest and most fundamental principles of the Cause of God is to shun and avoid entirely the Covenant-breakers, for they will utterly destroy the Cause of God, exterminate His Law and render of no account all efforts exerted in the past.
Abdu'l-Bahá
