Zarathustra proposed the existence of One Supreme God, Ahura Mazda, and so exalted monotheism. Ahura Mazda is the pivot round which the whole of creation revolves. He is the author of all good and He alone is worthy of praise and admiration as the highest. He is Omnipotent, Omnipresent and Omniscient. Lord Tennyson unwittingly echoes the 6,000-year-old thoughts of Zarathustra: "That God which ever lives and loves,/ One God, One Law, One element/ And one far off divine event/ To which the whole creation moves".
