Tao Te Ching

“Zarathustra—who never claimed for himself to be more than a man—was transfigured retrospectively by his followers when they had come to believe that from Zarathustra's seed a superhuman savior, the Saoshyant, was to be begotten at the end of Time.”

— Arnold Toynbee 1889 – 1975 CE
from An Historian's Approach to Religion (1956)
