There are many faiths and beliefs, I am a Christian but I do investigate other religions and the Yin and Yang theory appeals to me... These are my nieces two ... Willow and Austin, created in love, I have placed them sleeping peacefully in an egg shape enclosure, perhaps a womb and shaded the forms within Yin Yang. Note from Mr Google... The ubiquitous yin-yang symbol holds its roots in Taoism/Daoism, a Chinese religion and philosophy. The yin, the dark swirl, is associated with shadows, femininity, and the trough of a wave; the yang, the light swirl, represents brightness, passion and growth.Aug 2, 2013
