The 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-BaháHumanity has emerged from its former degrees of limitation and preliminary training. Man must now become imbued with new virtues and powers, new moralities, new capacities. New bounties, bestowals and perfections are awaiting and already descending upon him.
Abdu'l-BaháMay you become as the waves of one sea, stars of the same heaven, fruits adorning the same tree, roses of one garden in order that through you the oneness of humanity may establish its temple in the world of mankind, for you are the ones who are called to uplift the cause of unity among the nations of the earth.
Abdu'l-BaháThe spirit does not need a body, but the body needs spirit, or it cannot live. The soul can live without a body, but the body without a soul dies
Abdu'l-BaháAmong the greatest of all great services is the education of children, and promotion of the various sciences, crafts and arts. Praised be God, ye are now exerting strenuous efforts toward this end. The more ye persevere in this most important task, the more will ye witness the confirmations of God, to such a degree that ye yourselves will be astonished.
Abdu'l-Bahá
