大般涅槃經集解 63.75

63.75

案僧亮曰：上云當見為有，此說見之時也。以少見名因、全見名果，因名為得，果是所得。今以得為佛性者，因中說果也。

Sengliang comments: Above, it said that being seen in the future constitutes existence; here it states the time of seeing it. Slight vision is termed the cause, and complete vision is termed the fruit; the cause is named 'attaining', and the fruit is 'what is attained'. Here, taking attaining as buddhadhātu is speaking of the fruit within the cause.
