Great Monad separated into Duality, the Male and Female Principles in
nature; and then, by a process of biogenesis, the visible universe was
produced.

Popular Cosmogeny.--An addition, however, to this simple system had to
be made, in deference to, and on a plane with, the intelligence of the
masses. According to this, the Male and Female Principles were each
subdivided into Greater and Lesser, and then from the interaction of
these four agencies a being, named P'an Ku, came into existence. He
seems to have come into life endowed with perfect knowledge, and his
function was to set the economy of the universe in order. He is often
depicted as wielding a huge adze, and engaged in constructing the world.

his flesh became the soil; his sweat descended as rain; while the
parasites which infested his body were the origin of the human race.

B.C. 2698-2598, who built a temple for the worship of God, in which

came the Emperor Chuan Hsu, B.C. 2514-2436, of whom it is said that he
