大方廣佛華嚴經疏 8.24

8.24

7. Cultivation and realization: they are cultivated throughout all five stations, and only a Buddha brings them to ultimate completion. In relation to the causal stations, there are generally three designations: during the first incalculable eon, the power of giving and the others is still weak and is subdued by afflictions, so it is merely called pāramitā; from the second eon onward, its power gradually increases and can subdue afflictions, so it is called upa-pāramitā; during the third asaṃkhyeya, its power increases still further and can definitively subdue all afflictions, so it is called mahā-pāramitā. Therefore, throughout the context of this text it repeatedly speaks of 'vast pāramitās'.
