摩訶止觀 3.201

3.201

In the preceding two contemplations, on the causal stage there are teaching, practice, realization, and persons; on the resultant stage there is only their teaching, and there are no practice, realization, or persons. Why is this? Because the persons on the causal stage reduce the body to ashes and enter quiescence, sinking into emptiness and becoming utterly extinguished, unable to achieve the Buddha at the summit of the result; they are merely provisional expositions, so there is their teaching, but no practice, realization, or persons.
