The ocean is one body of water, but different parts of it
have particular designation -- Atlantic, Pacific, Mediterranean, Antarctic,
etc. If we consider the names, there is differentiation, but the water, the
ocean itself is one reality.
Likewise the divine religions of the holy Manifestations of God are in reality
one though in name and nomenclature they differ. Man must be a lover of the
light no matter from what day-spring it may appear. He must be a lover of the
rose no matter in what soil it may be growing. He must be a seeker of the truth
no matter from what source it come. (‘Abdu'l-Baha, from a talk in New York, dated
May 28, 1912; ‘The Promulgation of Universal Peace: Talks Delivered by
'Abdu'l-Bahá during His Visit to the United States and Canada in 1912’)
