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-BaháThe diversity in the human family should be the cause of love and harmony, as it is in music where many different notes blend together in the making of a perfect chord.
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
