大方廣佛華嚴經隨疏演義鈔 68.12

68.12

疏「即此所為亦是所以」者，所為成智慧，不住有為等。所以者，以有智慧故，不住有為也。餘可例知。

Regarding the Commentary's statement, "This purpose is itself the rationale": the purpose is to accomplish wisdom, not abiding in the conditioned, and so forth. The rationale is that because one possesses wisdom, one does not abide in the conditioned. The rest can be understood by analogy.
