Poetry is the embodiment of human esthetic consciousness. What is the source or origin of this consciousness, i.e. how is poetry generated is a subject much explored in the Chinese ancient poetics. The Chinese ancient psychological poetics dating back to over 2000 years tries to explore the esthetic interaction between spirits and objects based on the philosophic idea of Unity of the Heaven and Man, whereby poetry is thought to be generated in the esthetical relationship between subject and object, and is the flash of inspiration out of the collision between subject and object, as well as the fruit of wisdom generated from the subtle relationship between subject and object.
