The Seashell by Vladimir Kush

The sea and water is the prime source of life, a symbol of transformation, cleansing, and resurrection. The spiral form of a shell is a symbol of time: of the cyclic rhythms of the year, the faces of waning and waxing of the Moon, and the sun itself.
At tight spiral is a symbol of concealed force, a spool of energy. A spiral helix is a symbol of masculinity, a flat spiral a symbol of femininity.
The yin-yang is a type of double spiral; the dark yin is the female symbol, while the lightly coloured yang is the male symbol. Each half contains a seed of the other, which characterises the interdependence and harmony of two beginnings.
