Every kind of knowledge, every science, is as a tree: if the fruit of it be the love of God, then is it a blessed tree, but if not, that tree is but dried-up wood, and shall only feed the fire
Abdu'l-BaháReligion should unite all hearts and cause wars and disputes to vanish from the face of the earth; it should give birth to spirituality, and bring light and life to every soul. If religion becomes a cause of dislike, hatred and division, it would be better to be without it... Any religion which is not a cause of love and unity is no religion.
Abdu'l-BaháIn every aspect of life, purity and holiness, cleanliness and refinement, exalt the human condition . . . Even in the physical realm, cleanliness will conduce to spirituality.
Abdu'l-Bahá
