大方廣佛華嚴經隨疏演義鈔 78.14

78.14

疏「先明法身遍而叵見」者，叵，不可也。故〈出現品〉云「譬如法界遍一切，不可見取為一切；諸佛境界亦復然，遍於一切非一切。」

Regarding the commentary's "First clarifying that the dharmakāya is pervasive and yet impossible to see": po (叵) means impossible (不可). Thus the "Manifestation" chapter says: "Just as the dharmadhātu pervades everything, / yet cannot be seen and grasped as everything, / the realm of all buddhas is also like this: / it pervades everything, yet is not everything."
