 While the last three positions all had prominent advocates in China, the final position became dominant and was shared by Tiantai 天臺, Huayan, and Chan Buddhists. One obvious question is how this final position differs from the position of Mind-Only. Zongmi extends a line of argument common in Chinese Buddhism, which is to critique any form of dualism. Since nothing we experience is truly independent, simple, or unchanging, any metaphysics that posits substances with self-being requires a bifurcation between reality and appearances, or more specifically, between the substance itself and the various qualities or modes by which it appears. Buddhists argue against the coherence of any such division. This is the meaning of the common saying: “form is emptiness and emptiness is form.” Zongmi pushes this argument further to argue against any split between reality and illusion or between enlightenment and non-enlightenment. This leads to the claim that all sentient beings are already enlightened—what is needed is not to change reality or gain anything but just to realize that we are already where we need to be.
