首楞嚴義疏注經 6.229

6.229

畢陵伽婆蹉因觀痛覺，覺清淨心無覺無痛，遺身純覺，獲無學果。今云能覺身根與所覺觸互相假有，各無自性，義例相類，俱非圓觀，知無知異各有涯量，互不相冥，故為所揀。

Pilindavatsa, by contemplating the sensation of pain, realized that the pure mind is without sensation and without pain, and shedding the body to remain in pure awareness, attained the fruit of non-learning. Here it is said: the body faculty that perceives and the touch that is perceived borrow their existence from each other, each lacking self-nature; by analogous reasoning, neither is a perfect contemplation; the knowing and the non-knowing differ and each has its limit, not merging with each other; therefore it is selected out.
