Therefore, the Perennialists hold that God has assigned each of the “great world religions” to a specific sector or race of humanity, and “each is fully true in the sense that it provides its adherents with everything they need for reaching the highest or most complete human state.”4 Islam for the Arabs; Hinduism, Buddhism and Taoism for the peoples of the Far East, Christianity for the peoples of the West; Judaism for a selection of the Semitic peoples, and so on.
