摩訶止觀 7.182

7.182

Tenth: Freedom from Dharma-attachment. When one practices the above nine matters and passes beyond internal and external obstacles, one should attain entry into the real; yet if one fails to enter, it is because one abides in and clings to Dharma-attachment and cannot advance. The Abhidharma says: 'At the stage of heat one may still regress; if the five faculties are established and supreme patience generates the real, then regression is out of the question. If an attached mind arises at the stage of the summit, where one ought to enter but does not enter, one regresses to the four grave sins and five inexpiable offenses.' Both the shared and distinctive teachings have the meaning of 'summit falling.' One neither enters the stage nor falls into the two vehicles. The Mahāprajñāpāramitopadeśa says: 'The three samādhis are the stage of resemblance to the Way. Before the real is generated, one is prone to have Dharma-attachment; this is called “summit falling.”' Among people practicing the Way today, not one in ten thousand reaches this; yet when reaching this, one must skillfully protect oneself. At this stage there are no internal or external obstacles, only Dharma-attachment. Dharma-attachment is difficult to sever; if there is any delay, this is no small matter. It is like traveling under the same sail: one moves forward and one halts; to halt is to abide and cling. Furthermore, though one does not hit the sandbanks nor hit the shore, one halts because the wind has died down. Not hitting the sandbanks is a metaphor for having no internal obstacles; the shore is a metaphor for external obstacles. But when Dharma-attachment arises, the wind that abides nowhere dies down, and one neither advances nor regresses: this is called 'summit falling.'
