法華文句記 10.46

10.46

言如是者，謂說常壽。若得常壽，盡未來世必當過此，何但如是？今從實成來故且舉爾許，具在《玄》文過減不同。

Saying "like this" refers to preaching the permanent life span. If one attains the permanent life span, exhausting the future ages it will inevitably exceed this; why would it merely be "like this"? Now, coming from real attainment, he provisionally cites this much; the details are in the text of the Profound Meaning concerning the differences of exceeding and decreasing.
