This paper briefly reflects on the criticisms raised against the Chinese Buddhist theory of Buddha Nature. Instead of attempting to gain an understanding of the theory of Buddha Nature via logical analysis or empirical verification, I suggest that it may be best understood from the viewpoint of spiritual practice. And even so, it may not be appropriate to merely interpret this theory according to the doctrines of Early Buddhism or to evaluate it by means of textual research alone. Since the Chinese Buddhist theory of Innate Purity of Mind is based on a realization of value and ideals rather than mere factual description, we would encounter serious limitations by attempting to investigate this theory through theoretical reasoning alone. Innate Purity of Mind is a spiritual postulate of which the truth can only be actualized through practice. As is the case with argumentation in support of the existence of God, it is not easy to reach consensus on Innate Purity of Mind since its meaning and benefits largely depend on practical reason. Just as the belief in God makes it possible for a follower to experience peace and happiness, the theory of Innate Purity of Mind allows a practitioner to experience peace and happiness, too. Yet, the true meaning of Innate Purity of Mind, just like the true meaning of God, can only be revealed once the experience of peace and happiness has been achieved.
