Taiji or Tai chi is a Chinese cosmological term for the "Supreme Ultimate" state of undifferentiated absolute and infinite potential, the oneness before duality, from which yin and yang originate. It is believed that the organization of qi in this cosmology of yin and yang has formed many things.Included among these forms are humans. Many natural dualities (such as light and dark, fire and water, expanding and contracting) are thought of as physical manifestations of the duality symbolized by yin and yang.

In feng shui, it is said that your soul is the colors that you are most inclined towards. My tendency is yellow color and I think I can show my soul with yellow and my anger and anxiety is blue. In this piece, these two moods are showing me.

In fact, my bad and good moods are in the shape of a circle and they are together, and this complexity inside me is like the complexity of these two moods in each other.
