This paper was originally presented to the 27th International Millennium Congress, organized by the American Biographical Institute and British International Biographical Centre in July, 2000, at Washington D.C., USA. In a non-philosophical conference, this philosophical paper's main concern is to explain the essential meaning behind the poetic language. It begins with an analysis of the Taoist paradox, why the ultimate truth or the Tao is ineffable. The main body of the discussion is devoted in the following sections: 1. The philosophy of non-verberization; 2. Creativity of mind; 3. Self-realization as the metaphysics of poetry. The aim is to prove that, among the traditional Three Teachings, the quest for universal harmony is always the ultimate goal and the highest value of humanity. (The author wishes to thank the National Science Council of the Republic of China for the financial assistance provided to cover all expenses for attending the conference.)
