成唯識論述記 4.329

4.329

述曰：四智俱善，亦非界攝，非有漏故；有漏是界義故；界是縛義故。又彼何故非繫縛者？世尊已捨苦、集二諦名世尊故。何故無苦、集？有漏諸戲論種已永斷故。即有漏法名為戲論，無漏法名不繫法，故非同戲論，故正實趣生唯異熟心、心所。

The Commentary states: The four wisdoms are all wholesome; they are also not subsumed under the realms (dhātu) because they are not tainted. For "tainted" is the meaning of "realm"; "realm" has the meaning of "bondage". Furthermore, why is he not bound? Because the World-Honoured One has already abandoned the two truths of suffering and origination, he is called the World-Honoured One. Why is he free from suffering and origination? Because all tainted seeds of proliferation have been permanently severed. That is, tainted phenomena are called proliferation (prapañca), and untainted phenomena are called unbonded phenomena; therefore they are not the same as proliferation. Hence the true, real destinies and realms are only the retribution mind and mental factors.
