Love is the most great law that ruleth this mighty and heavenly cycle, the unique power that bindeth together the divers elements of this material world, the supreme magnetic force that directeth the movements of the spheres in the celestial realms
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-BaháThe mind and spirit of man advance when he is tried by suffering. ... so suffering and tribulation free man from the petty affairs of this worldly life until he arrives at a state of complete detachment.
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
