大般涅槃經義記 6.165

6.165

三就從因趣果以釋，明光行業足者名果，是名世義，舉世語義。下約顯法，「所言光者，名不放逸，是起行心。業名六度，是所起行」此二是因，得菩提果。

The third explains it in terms of proceeding from cause to fruition: clear light, karma, and conduct, being complete is called fruition—this is the worldly meaning, raising the conventional linguistic meaning. Below, it explains the Dharma accordingly: 'That which is called light is called heedfulness, which is the mind that arouses practice. Karma is called the six pāramitās, which are the practices aroused'—these two are the causes, attaining the fruition of bodhi.
