摩訶止觀 5.185

5.185

經又六句：「不生生亦不可說，生生亦不可說，生不生亦不可說，不生不生亦不可說，生亦不可說，不生亦不可說。」按：此六句明無生門破法遍。若破思議惑，用前四句；若破不思議惑，用後二句。何者？思議惑雖多，不出界內、外。界外惑附體生，故言「不生生」；界內惑是枝末，故言「生生」。此惑紛綸，並是所化之境，為此境故，施自在生。所化既不可得，何處有能化？能所俱亡，是故「不生生、生生俱不可說」。若破思議解，此解雖多，不出界內、外。界內解，止遣分段，故言「生不生」；界外解，雙遣分段、變易，故言「不生不生」。此解淺深，故有種種自行因果。理尚非一，寧有種種？今遍唾破，故言「生不生不可說，不生不生亦不可說」。

The sūtra also presents six phrases: "Non-arising arising is ineffable; arising arising is ineffable; arising non-arising is ineffable; non-arising non-arising is ineffable; arising is ineffable; non-arising is ineffable." Note: these six phrases clarify how the gate of non-arising breaks phenomena completely. If breaking conceivable afflictions, use the first four phrases; if breaking inconceivable afflictions, use the last two phrases. Why? Conceivable afflictions, though many, do not go beyond the inside and outside of the three realms. Afflictions outside the realms arise adhering to the essence, hence it says "non-arising arising"; afflictions inside the realms are branches and twigs, hence it says "arising arising." These afflictions are tangled and manifold, and all are the realm of those to be converted; for the sake of this realm, birth at ease is displayed. Since those to be converted cannot be apprehended, where could there be one who converts? Both active and passive vanish; therefore "both non-arising arising and arising arising are ineffable." If breaking conceivable understanding, such understanding, though manifold, does not go beyond the inside and outside of the realms. Understanding inside the realms only dispels fragmented [birth and death], hence it says "arising non-arising"; understanding outside the realms dispels both fragmented and transformative [birth and death], hence it says "non-arising non-arising." Because this understanding has depths and shallows, there are various causes and effects in one's own practice. The principle is not even one; how could there be varieties? Now, spitting upon and breaking them completely, it says "arising non-arising is ineffable, and non-arising non-arising is also ineffable."
