A bird perches upon the loftiest branch and builds there its nest with consummate beauty and skill. All the grains and seeds of the meadows are its wealth and food; all the fresh water of mountain springs and rivers of the plain are for its enjoyment. Truly, this is the acme of material happiness, to which even a human creature cannot attain. This is the honor of the animal kingdom. But the honor of the human kingdom is the attainment of spiritual happiness in the human world, the acquisition of the knowledge and love of God. The honor allotted to man is the acquisition of the supreme virtues of the human world. This is his real happiness and felicity. But if material happiness and spiritual felicity be conjoined, it will be “delight upon delight,” as the Arabs say. We pray that God will unite the East and the West in order that these two civilizations may be exchanged and mutually enjoyed. ‘Abdu’l‑Bahá, The Promulgation of Universal Peace.
