首楞嚴義疏注經 5.257

5.257

念，觀也。知，覺也。因痛起觀，觀我此身有於知覺覺此深痛。然雖起觀，觀覺及痛，觀清淨心無痛無覺，此根塵念慮，妄身心有、真淨心無。又更觀察痛覺之念、淨心之覺，即成二覺，從何而有？一身二覺應成兩佛，故知此覺皆悉虛幻，清淨心中一無所得。

'Reflected' means contemplated. 'Knowing' means awareness. Because of the pain, he aroused contemplation, contemplating that in this body of mine there is an awareness that is aware of this intense pain. Yet although he aroused contemplation, contemplating the awareness and the pain, he contemplated that the pure mind is free of pain and free of awareness; this thought and deliberation of faculties and dusts exists in the deluded body and mind, but does not exist in the true, pure mind. He further contemplated: the thought of the awareness of pain and the awareness of the pure mind would constitute two awarenesses—from whence do they arise? If one body had two awarenesses, it would have to become two Buddhas. Therefore, he knew that these awarenesses are entirely illusory, and within the pure mind not a single thing can be apprehended.
