摩訶止觀 7.110

7.110

多修六度功德善本，似羊身肥；勤觀無常，諸惡業壞，恒被狼怖，如羊無脂。是名「修事般若相」。自行教他，讚法讚者，稱十方佛為證為救。諸佛威加，離障解脫，即與四種十慧相應。是為事油助增道明（云云）。

Cultivating extensively the six perfections, merits, and roots of goodness is like a sheep's body growing fat; diligently contemplating impermanence, destroying all evil karmas, constantly terrified by wolves, is like a sheep having no fat. This is called 'the characteristics of cultivating phenomenal prajñā.' Practicing personally and teaching others, praising the Dharma and praising those who practice it, invoking the Buddhas of the ten directions as witnesses and saviors. With the Buddhas' majestic aid, freed from hindrances and liberated, one then corresponds with the four kinds of ten wisdoms. This is the oil of phenomenal practice helping to increase the light of the Way, and so forth.
