O true companions! All humankind are as children in a school, and the Dawning-Points of Light, the Sources of divine revelation, are the teachers, wondrous and without peer. In the school of realities they educate these sons and daughters, according to teachings from God, and foster them in the bosom of grace, so that they may develop along every line, show forth the excellent gifts and blessings of the Lord, and combine human perfections; that they may advance in all aspects of human endeavour, whether outward or inward, hidden or visible, material or spiritual, until they make of this mortal world a widespread mirror, to reflect that other world which dieth not. (‘Abdu’l-Baha, ‘Selections from the Writings of `Abdu'l-Bahá’; The Compilation of Compilations, vol. I, Excellence in All Things)
