仁王般若經疏 3.88

3.88

「巧用不證，不沈不出不到是方便觀，譬如水之與波不一不異，乃至一切行波羅蜜、禪定、陀羅尼不一不二故。而二行成就，以四阿僧祇劫行行故，入此功德藏門。無三界業習生故，畢故不造新。以願力故變化生一切淨土，常修捨觀故登鳩摩羅伽位，以四大寶藏常授與人。」

"Skillfully functioning without realizing, neither sinking nor emerging nor arriving—this is the contemplation of upāya. Just as water and waves are neither one nor different, and so forth up to all practices, pāramitās, dhyāna concentrations, and dhāraṇīs being neither one nor dual. Thus the two practices are fulfilled, and because they cultivate practice for four asaṃkhyeya kalpas, they enter this gate of the treasury of virtues. Because karmic residues of birth in the three realms are absent, they finish the old and do not create the new. Through the power of vows they transform and take birth in all pure lands, and because they constantly cultivate the contemplation of relinquishment, they ascend to the stage of kumārabhūta, constantly bestowing the four great treasuries of jewels upon people."
