摩訶止觀 5.244

5.244

若待非生非無生而有心生者，《論》云：「從因緣生尚不可，何況無因緣？」又此無因為有？為無？若有，還是待有；若無，還是待無；何謂無因？若言有性，性為有？為無？性若是有，為生？非生？若生，已是生，何謂為性？若無生，云何能生？

If mind arises in dependence on neither arising nor non-arising, the Treatise states: 'Arising from causes and conditions is not even possible, how much less without causes and conditions?' Furthermore, does this absence of cause exist, or does it not exist? If it exists, it is still depending on existence; if it does not exist, it is still depending on nonexistence; how could it be called without cause? If one says it possesses a nature, does this nature exist or does it not exist? If the nature exists, is it arisen or non-arisen? If it is arisen, it is already an arising, so how could it be called a nature? If it is non-arisen, how could it produce anything?
