瑜伽師地論略纂 9.83

9.83

論云「若先已得，未令現前，但由修習彼種類法，當令現前，令轉清淨鮮白生起，名修故淨」者，此即法智時，其類智種子亦成就故，名先已得。由得修習彼法智種子時，即資種類智種法，至類智時，此種子能生類智，令轉清淨鮮白生起，名修故淨。即法智時，修類智種子令清淨，復生類智也。又如見道前熏增無漏種，入見道生法智等是。又種子成就，是由修故名得；現行成熟，名由修故習；自在成熟，名由修故淨：是三成熟也。若已生惑能斷，名由修故遣；未生諸惑能令不生，了知如病等，名由修故知。

Where the treatise says, "If previously already obtained but not yet brought to manifest presence, merely by cultivating dharmas of that kind, one will cause it to manifest before one, causing it to arise increasingly pure and bright, which is called purified through cultivation": this means that at the time of the wisdom of phenomena, because the seeds of its subsequent wisdom are also accomplished, it is called 'previously already obtained'. Because when cultivating those seeds of the wisdom of phenomena, one assists the dharmas of seeds of that kind of wisdom, by the time of the subsequent wisdom, these seeds are capable of generating subsequent wisdom, causing it to arise increasingly pure and bright, which is called 'purified through cultivation'. That is, at the time of the wisdom of phenomena, cultivating the seeds of subsequent wisdom makes them pure, and further generates subsequent wisdom. Furthermore, it is like perfuming and increasing the untainted seeds prior to the path of seeing, so that upon entering the path of seeing, the wisdom of phenomena and so forth are generated. Furthermore, the accomplishment of seeds is called 'obtained through cultivation'; the maturation of manifest activity is called 'practised through cultivation'; and the maturation of mastery is called 'purified through cultivation': these are the three maturations. If already arisen afflictions can be severed, it is called 'dispelled through cultivation'; if unarisen afflictions can be kept from arising, comprehending them as like an illness and so forth, it is called 'known through cultivation'.
