Love manifests its reality in deeds, not only in words - these alone are without effect.
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-BaháThe mere size of the brain has been proved to be no measure of superiority. The woman has greater moral courage than the man; she has also special gifts which enable her to govern in moments of danger and crisis. If necessary she can become a warrior.
Abdu'l-BaháTo promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
Abdu'l-BaháTherefore, in this world he must prepare himself for the life beyond. That which he needs in the world of the Kingdom must be obtained here. Just as he prepared himself in the world of the matrix by acquiring forces necessary in this sphere of existence, so, likewise, the indispensable forces of the divine existence must be potentially attained in this world.
Abdu'l-Bahá
