首楞嚴義疏注經 2.447

2.447

若離燈外別有圓影，旁見餘物何無影出？色若離見別有體者，不合眚眼見於圓影。几，案屬。筵，席也。

If there were a circular halo separately existing apart from the lamp, why would no halo emerge when looking sideways at other things? If the color had an existence apart from seeing, the cataract-stricken eye ought not to see the circular halo. 'Ji' belongs to the category of small tables; 'yan' is a mat.
