15.79

堅於離染地，異生不造生，聖不造生後者，不退性名堅，此通異生及聖也。彼於離染地若不退，異生不造生業，以不退性離此地染，於第二生必不生故，故無生業，容造餘三。不退聖人於離染地不造生後，以不退性必無還生下諸地故，故無生後，容造餘二。并欲有頂退者，離欲聖人及有頂聖雖有退墮，而亦不造欲界有頂生、後二業，同前不退聖故，頌致并言。夫從離欲有頂退者必是退果，諸退果者必不命終，還修得果故，於離染地永更不生，故無生後業也。

Regarding "The steadfast, in a stage free from passion, / do not produce [karma for] the next [life] if ordinary beings, / while noble ones do not produce [karma for] the next or subsequent [lives]": The nature of non-retrogression is called "steadfast"; this applies to both ordinary beings and noble ones. If they are non-retrogressing in a stage free from passion, an ordinary being does not produce karma [to be experienced in] the next life, because having the nature of non-retrogression and being free from the passion of this stage, they will definitely not take birth in the second life; hence they have no karma for the next life, but can produce the remaining three. A non-retrogressing noble person, in a stage free from passion, does not produce [karma for] the next or subsequent lives, because having the nature of non-retrogression, they definitely never take birth again in the lower stages; hence they have no [karma for] the next or subsequent lives, but can produce the remaining two. Regarding "along with those fallen from desire and the summit of existence": Although a noble person free from desire [for the Kāmadhātu] and a noble person at the summit of existence may fall back, they also do not produce karma for the next or subsequent lives in the Desire Realm or the summit of existence, being identical to the aforementioned non-retrogressing noble ones; hence the verse includes the word "along with". Those who fall back from being free from desire or from the summit of existence must fall back from the fruit; and all who fall back from the fruit definitely do not die [in that state], but cultivate again and regain the fruit; therefore they never again take birth in a stage free from passion, and hence they have no karma for the next or subsequent lives.
