大方廣佛華嚴經隨疏演義鈔 84.83

84.83

大文第八毫光示益分。疏「即此能入亦是所益」者，此有兩重能所：一遮那光照是其能益，得解等十即是所益；二此解三昧等是其能入，法身色身等即是所入。不因佛光不得能入，不得能入安得所入？故能所入皆是成益也。

The eighth major section is the section on revealing benefit through the light of the ūrṇā. Regarding the Commentary's statement, "This very capacity to enter is also the benefit received," there are two layers of subject and object: first, Vairocana's illumination is that which benefits, and the ten [attainments] such as gaining understanding are the benefits received; second, these understandings, samādhis, and so forth are the capacity to enter, and the dharmakāya, rūpakāya, and so forth are that which is entered. Without relying on the Buddha's light, one could not obtain the capacity to enter; without obtaining the capacity to enter, how could one attain that which is entered? Therefore, both the capacity to enter and that which is entered constitute the benefit achieved.
