仁王護國般若波羅蜜多經疏 3.220

3.220

The commentary explains: "Prior to the kṣānti of practice" clarifies [the time] outside the kalpas. "Passing through ten thousand kalpas" is the time traversed. This clarifies those who proceed directly, which is not like the eighty thousand, sixty thousand, forty thousand, twenty thousand, and ten thousand kalpas in the Nirvāṇa [Sūtra], because here it is sudden while there it is gradual, and thus there is a distinction. "Practising the ten virtuous deeds" is the practice performed: the three of body, four of speech, and three of mind make ten. "With regress and progress" clarifies that they are indeterminate. From here, the second part presents a simile to explain and substantiate [it].
