金光明經文句記 4.100

4.100

二、「若體」下，體本虛叵得。妄執有生，生實不生，故生名虛偽。既本不生，故見身寂滅。叵，猶不可也。

Second, below the words "if realizing," realizing that it is fundamentally empty and cannot be obtained. Deludedly grasping that there is arising, in reality there is no arising; hence arising is called deceptive and false. Since fundamentally there is no arising, one sees that the body is calm and extinguished. Po (叵) is equivalent to "cannot" (buke).
