27.113

「有學身中至故不名明」者，釋第四句。有學身中有愚闇故，惑未除盡。於三明中雖有前二，由無後故，不立為明。雖有暫時伏滅愚闇，後還被蔽，故不名明，愚闇永無方名明故。

On "Within the person of a śaikṣa ... hence they are not called vidyās": this explains the fourth line. Because there is the darkness of ignorance in the person of a śaikṣa, the defilements have not yet been completely eradicated. Although the first two are present among the three vidyās, because of the absence of the last one, they are not established as vidyās. Although there is a temporary suppression and eradication of the darkness of ignorance, later they are still obscured by it, and therefore are not called vidyās, for it is only when the darkness of ignorance is permanently absent that it is called a vidyā.
