Jízàng criticized numerous Chinese Buddhists for their unwarranted metaphysical assumptions. He ultimately rejects all metaphysical assertions of being and non-being as dogmatic conceptual confusions. Thus according to Hsueh-Lu Cheng, for Jízàng:True wisdom (prajña) is the abandonment of all views. Chi-tsang argues that metaphysical speculation of Being and Nothingness is a disease (ping). It is the root of all erroneous or perverted views. The cure of the disease lies not so much in developing a new metaphysical theory as in understanding the proper nature and function of human conceptualization and language. Chi-tsang, following Nagarjuna, claims that the very language men create and use plays a trick on them and destroys their "eyes of wisdom." Enlightened men should discard conceptualization so as to avoid being taken in by this trick. Emptiness, for Chi-tsang, is a medicine (yao) for curing the "philosophical disease."Jízàng called his philosophical method "deconstructing what is misleading and revealing what is corrective". He insisted that one must never settle on any particular viewpoint or perspective but constantly reexamine one's formulations to avoid rectification of thought and behavior.
