 To see what this means and how it is to be actually experienced requires careful unpacking. Tiantai meditation practice represents a surprising and innovative repurposing of certain earlier Buddhist motifs, just as the Tiantai doctrinal positions do. In this case, the key motif to be repurposed is the pan-Buddhist emphasis on the impermanence of mental states. Here this view is pushed to the extreme, also found in many earlier schools, of regarding apparent all mental continuity as a misperception of what is really a succession of radically distinct and extremely brief moments of mental activity. The traditional Buddhist emphasis on the sole reality of the present instant of experience is also radicalized in this move and, in a typical Tiantai manner that by now should seem familiar, both of these familiar Buddhist claims are thereby repurposed and even reversed, as we shall see.
