To master metaphysic of middle way of reality for Tien-Tai Zhi-Zhe, is to develop the meanings of essence of phenomenon. Discussing in the dimension of proving metaphysic of reality is to display the way of metaphysical annotation of phenomenon which is the same as essence. In the field of the forms of understanding and enlightening reality, it will develop the form of clearly observing reality. That is to develop the method of the annotation having a clear view of the truth perfectly and immediately. The methods are displayed by the way of the perfect and sudden of observing reality through phenomenon. Applying the forms of Perfect is to fuse, complete and fill the different dimensions of idea, reason, concept, perception etc. That is compatible with incredible reality of the doctrine of the single vehicle taught in the Lotus Sutra. Consequently, this paper would apply two kinds of route to develop the explanatory meanings of Tien-Tai Zhi-Zhe to the intuition method of middle way of reality. In the beginning, through three kinds of dimension this paper can prove the thought of Zhi-Zhe establishing the metaphysics of reality.: the first is the foundation of the doctrine of the single vehicle taught in the Lotus Sutra; the second is the annotation of phenomenon which is the same as essence; the third is the theory of idealism of transcending the subjective and objective. Next, there are four dimensions to develop the annotation of Zhi-Zhe establishing the methods of observing reality. The first is the application of dialectical method of becoming one. There are five ways to develop the perfect meanings of “not different and not two”: first way is the integration of the subjective and objective; second way is the integration of conditioned genesis and reality; third way is the integration of emptiness and existence; fourth way is the integration of interdependence and transcendent; fifth way is the the integration of conception and inconceivable. The second is the annotation of the perfect and sudden of Lotus sutra. The third is to develop yi nann san chian of the perfect and sudden of observing reality. The fourth is the methodological application of four kinds of observation from the gradual to the perfect. With the above two kinds of route this paper can explain the core meanings and the ultimate truth of Tien-Tai Zhi-Zhe developing the intuition method of middle way of reality.
