According to the fundamental laws which We have formerly revealed in the Kitáb-i-Aqdas and other Tablets, all affairs are committed to the care of just kings and presidents and of the Trustees of the House of Justice. Having pondered on that which We have enunciated, every man of equity and discernment will readily perceive, with his inner and outer eyes, the splendours of the day-star of justice which radiate therefrom. (Baha’u’llah, ‘Tablets of Bahá'u'lláh revealed after the Kitab-i-Aqdas’; The Compilation of Compilations, Vol. I, The Establishment of the Universal House of Justice)
