Chinese astrology, like almost all other Chinese disciplines, reposes on four main pillars, which call for some succinct comments. These pillars are: the concept of Yang and Yin, the notion of the Five Elements, the patterns of all cosmic transformations, and finally the Chinese calendar.
 
 

The workings of the universe is probably the most important, yet also the most ignored, topic. There have been various philosophies and explanations for the same in ancient scriptures of various civilisations. One of the most significant being the Chinese philosophy on the natural phenomenon of the universe, or the Tao, as mentioned in I Ching (the foundation of Chinese philosophy also known as the Book of Changes). The book explains the metaphysical workings of the entire universe and is the origin of what is called the Yin-Yang school of Chinese thought.
