The chief point in the teachings of holy Zarathustra is the path of goodness; and he separates goodness from badness, calling God the All-good and Satan the All-bad. According to this point of view of the Master, God was, as He is always, the Ideal of worship; and nothing but good can be praised, and none but the good worshiped, and all which is bad naturally leads man astray and veils from his eyes all good. The spirit of evil was personified by the Master, as it had already been personified by the ancients, as Satan.
