A sacred symbol of an organ associated with birth resembling omega

As a result of analogous thinking Birth = Creation, then the organs associated with birth have been projected as partaking in creation. Birth of a new life-form begins with reproduction of union of a pair as male-female. They depend upon their reproductive organs. Their external sex-organs are the first to initiate reproduction and both are considered auspicious. Reproduction leads to pregnancy of the female whose internal organ becomes the organ where the fetus grows until an independent life-form issues into the world. As this organ resembles the letter Omega of the Greek alphabet those who believe in prudery speak of it as the omega-shaped organ. Nevertheless, it is the place where a new life form develops and it is considered auspicious. Everything promoting the formation of a life-form is considered auspicious.
