Curved Jewel Amulets
Tamaonooya (Parent of the Jewel) Shrine's speciality is curved drop shaped jewels that look like they could be used to make up the symbol for Taoism, which in Japan (far more realistically I fee) contains three curved drops, Yin, Yang and infancy perhaps.
These curved jewels (maga tama) , one of which my wife can be seen purchasing above, were worn by ancient Japnnese, and Japanese gods, on necklaces. They were chewed and spat into the well of the middle of heaven to create gods. In this way the creative "word" of Japanese deities is a visio-corporeal one: curved-jewel spit.
I have also found out that the the word for the three dropped symbol, mitsudomoe, means a sexual "threesome". The truth, however, contra Taoism, is that life is not entirely sexual since yin, at least, is as complemented by children as yin is by yang.
See also the effigy of humans (ningen) in the manga "3x3 Eyes", or "Sazan Eyes," which is also three people conjoined at the waste. I wonder if Wu eventually has children with Pai, or with classmate (who Pai then inhabits and becomes at last human).
The self is generally a trinity: the dream of spectator and spectated, or narrated and heard, and the World that is pulling the striggs. But, this leaves for the posibilty of a pentogram of self positons. NLP?
