In 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-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-BaháTo promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
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-Bahá
