Make ye then a mighty effort, that the purity and sanctity which, above all else, are cherished by ‘Abdu'l-Bahá, shall distinguish the people of Bahá; that in every kind of excellence the people of God shall surpass all other human beings; that both outwardly and inwardly they shall prove superior to the rest; that for purity, immaculacy, refinement, and the preservation of health, they shall be leaders in the vanguard of those who know. And that by their freedom from enslavement, their knowledge, their self-control, they shall be first among the pure, the free and the wise. (‘Abdu’l-Baha, "Selections from the Writings of ‘Abdu'l-Bahá"; The Compilation of Compilations, vol. I, Excellence in All Things)
