The Pindanuyukti is gone. The currently available literature on the subject does not seem to have any connection with the Nandy Sutra's mention of the Nuyukti.
Acharya Bhadrabahu has promised to write 10 Nuyuktis in the Avashyak Nuyukti. The order in which these Nuyuktis are written is as follows: 1. Avashyak 2. Dasha Vaikalik 3. Uttara Adhyayan 4. Acharang 5. Sutra Kritang 6. Dasha Shruta Skandh 7. Brihat Kalp 8. Vyavahar 9. Surya Prajnapti 10. Rishi Bhashit. Haribhadra has also mentioned the Nuyukti of Devendrastava etc. in the explanation of the word 'Ishibhasianam cha'. Currently, only eight of these ten Nuyuktis are available. It seems likely that Bhadrabahu promised to write ten Nuyuktis in the Avashyak Nuyukti but was unable to create the last two. Another possibility is that, like other Agam literature, some Nuyuktis have also been lost over time. In this context, Dr. Sagarmalji Jain's opinion is worth reading: "It seems that after seeing some mentions in the Surya Prajnapti that are contrary to Jain moral principles and the mention of controversial figures like Narada, Mankhali Gaushalak etc. in the Rishi Bhashit, Acharya Bhadrabahu may have postponed the idea of writing Nuyukti on them even after promising to do so. Or it is also possible that Nuyuktis were written on these two texts but due to the mention of controversial topics, they were kept out of reading and study, and as a result, they became extinct over time due to neglect."
In addition, there is also independent existence of Pindanuyukti, Oghanuyukti, Panchkalpanuyukti and Nishthanuyukti etc. According to Dr. Ghatge, these are supplementary Nuyuktis of Dasha Vaikalik Nuyukti, Avashyak Nuyukti, Brihat Kalp Nuyukti and Acharang Nuyukti respectively, but the point to be considered is whether these Nuyukti texts are supplementary or independent works. Pindanuyukti is an independent work, its detailed discussion will be done in the introduction later.
Oghanuyukti cannot be called a supplement to Avashyak Nuyukti because the entire chapter of Asvadhyayan Nuyukti in Avashyak Nuyukti is in Oghanuyukti. If it were a supplementary text to Avashyak Nuyukti, there would not have been so many verses repeated. Detailed thinking about this will be done in the fifth volume of Nuyukti literature.
