摩訶止觀 5.168

5.168

一種禪師不許作觀，唯專用止，引偈云：「思思徒自思，思思徒自苦；息思即是道，有思終不覩。」又一禪師不許作止，專在於觀，引偈云：「止止徒自止，昏闇無所以；止止即是道，觀觀得會理。」兩師各從一門而入，以己益教他。學者則不見意，一向服乳，漿猶難得，況復醍醐？

One kind of meditation master does not permit practicing contemplation and exclusively employs calming, quoting a verse: 'Thinking, thinking is in vain to think to oneself; / Thinking, thinking is in vain to suffer oneself. / Ceasing thought is precisely the path; / As long as there is thought, one will never see.' Another meditation master does not permit practicing calming and focuses exclusively on contemplation, quoting a verse: 'Calming, calming is in vain to calm oneself; / Dull and dark without cause. / Calming, calming is not the path; / Contemplating, contemplating one comes to accord with the principle.' Each of the two masters entered through a single gate and teaches others based on their own benefit. Students do not see the intent; exclusively consuming milk, they can hardly obtain buttermilk, let alone clarified butter.
