摩訶止觀 6.111

6.111

如是等世智之法，精通其極，無能逾，無能勝，咸令信伏而師導之。出假菩薩欲知此法，當別於通明觀中勤心修習。大悲誓願，精進無怠；諸佛威加，豁然明解，於世法藥永無疑滯。然世法藥非畢竟治，屈步移足雖垂盡三有，當復退還。故云：「凡夫雖修有漏禪，其心行穿如漏器；雖生非想當復退還，如雨彩衣其色駮脫。」世醫雖差，差復還生，此之謂也。

Mastering such methods of worldly wisdom to the utmost, with none able to surpass or defeat him, he causes all to submit in faith and take him as master and guide. If a bodhisattva emerging into the provisional wishes to know these dharmas, he should diligently cultivate them separately within the contemplation of penetrating luminosity. With the vow of great compassion and vigor without indolence, through the empowered aid of all Buddhas, he suddenly comprehends them clearly, forever free of doubt or stagnation regarding mundane Dharma-medicines. Yet mundane Dharma-medicines are not an ultimate cure; though one bends one's pace and moves one's feet almost to the end of the three realms of existence, one will still fall back. Therefore it is said: 'Although ordinary persons cultivate contaminated dhyāna, their mind's practice is punctured like a leaky vessel; though born in [the heaven of] neither-perception-nor-non-perception, they will still fall back, like a dyed garment in the rain whose colors peel and fade.' Though a worldly physician cures [a disease], once cured it recurs—this is what is meant.
