Gommatasara Karmakanda - 307
The lifespan that is being experienced is called "bhujyaman" and the lifespan that is being bound for the future is called "badhyaman". In relation to these two, a being cannot take the vow of "deshvrat" if it has the essence of a "narakayu" lifespan, and cannot take the "mahavrat" if it has the essence of a "tiryanchayu" lifespan. A being cannot ascend the "kshapka" श्रेणी if it has the essence of a "devayu" lifespan. The destruction of the essence of these 7 natures, including the four "anantaanubandhi" kshayas and the three "darshanamohaniya", occurs in one of the four "gunasthanas" of "asanyata" etc., leading to "kshayik samyagdristi".
Now, the order of their (the above 7 natures) destruction is explained:
While destroying these seven natures, one first performs "trikaran". Among them, in the final moment of the "antarmuhurt" time of "anivrittikaran", one simultaneously disconnects the four "anantaanubandhi" kshayas, i.e., five "kapayarupa" parinamas occur from among the 12 kshayas of "apratyakhyan" etc. and the 9 "nokshayas". After this, one takes rest for an "antarmuhurt" and then makes an effort to destroy "darshanamoha". First, one performs three "karans" - "adhahpravrittikaran", "apuurvakaran", and "anivrittikaran". Here, in the "antarmuhurt" time of "anivrittikaran", one divides it into parts and lets one part pass without multiple parts. From the first moment of that one part, one destroys the three natures in order. In the first moment, one destroys the "mithyatva" nature, then destroys "samyagmithyatva". After that, one destroys the "samyaktva" nature and then attains "kshayik samyaktva". A detailed explanation of this is found in the "Labdhisara Kshapanasara" text and in "Jayadhwala" chapter 13.
Now, Nemichandracharya himself explains the order of the destructible natures in the "kshapkanivrittikaran" gunasthana:
"Solatthekkigichakkan chadusekkan badare ado ekkan. Khine solas jogen, bavantariteruvattamte." || 337 ||
Meaning: In the 9 parts of the "kshapkanivrittikaran" gunasthana, the essence of 16, 8, 9, 1, and 6 natures is destroyed in order, and in the remaining four parts, the essence of one nature is destroyed in each. In the "sukshmasamparaya" gunasthana, the essence of one nature is destroyed, in the "khinakshaya" gunasthana, there is no destruction of essence, and in the "ayogi" gunasthana, in the last two moments, the essence of 72 natures is destroyed in the penultimate moment and the essence of 13 natures is destroyed in the ultimate moment.
Special Note: Here, the "upashmana" and "kshapan" methods are explained in relation to each other, but first, the "upashmana" method is explained.
