I recently became interested in Acupuncture, which lead to me researching about Traditional Chinese Medicine and Yin and Yang.
The origins seem of Yin and Yang seem to be complex and numerous. There are also many different interpretations.
My interpretation is that Yin is feminine and Yang is masculine. There must be a balance of them both, for example with cool - heat, slow - fast with Yin and Yang respectively. Yin and Yang oppose and complement each other. The balance of Yin and Yang create oneness.
Alternative therapies can help restore Yin and Yang.
I do not focus on this in my psychic readings but my healing component to readings helps restore this balance.
