## 10. Sarvarthasiddhi
It is not unreasonable to believe that the Sarvarthasiddhi commentary on the Tattvarthasutra was written before the 8th century Vikram era, perhaps in the early 6th century or even earlier, as many commentaries and annotations were already in circulation.
Although Dharmasagargani, a disciple of Balissah, doubts that Swati composed the Tattvarthasutra, this is not his definitive opinion. It is merely a possibility. As he states in his words, "Balissah's disciple Swati is considered to have composed the Tattvartha and other works." Therefore, this cannot be given much importance.
We have reviewed five opinions so far. Only one major opinion remains, which needs to be considered from three perspectives: name, tradition, and time.
We have already mentioned in the beginning, with citations, that Acharya Virasen, Acharya Vidyānanda, and Acharya Vadiraj declare Acharya Gṛddhapichchha as the author of the Tattvarthasutra. These mentions are relatively ancient. However, apart from these mentions, all other mentions found in the Digambara tradition show a variety of names, considering Gṛddhapichchha as a secondary or another name. We have already mentioned some of these prominent mentions under the heading "Other Opinions."
Similarly, there is a prominent opinion based on the Nandisangh's lineage. Two lineages of Nandisangh are available: one in Sanskrit and the other in Prakrit. The Sanskrit lineage states that Acharya Umaswati is the author of the Tattvarthasutra.
Here, we need to consider why there is so much disagreement about the author's name and what his real name is.
We have already presented the citations from inscriptions 105 and 108 found in Shravanabelagola. They are estimated to be from the years 1320 and 1355 of the Saka era. Two other inscriptions from the years 1037 and 1085 of the Saka era are also available there, which are listed as numbers 47 and 40 in the Jain inscription collection, volume 1. Inscription number 47 states:
"In the lineage of Shri Gautam Ganadhar, the prominent Acharya Padmanandi of the Nandisangh, whose other name was Kondakunda, existed. Then, in his lineage, Acharya Umaswati, whose other name was Gṛddhapichchha, existed. His disciple was Balakapichchha, and Balakapichchha's disciple was Gunanand."
Inscription number 40 states:
"After Gautam Ganadhar, the fifth Shrutakevali, Bhadrabah, and his disciple Chandragupta existed. After them, in their lineage, Padmanandi existed. His other name was Kondakunda. Then, in his lineage, Acharya Gṛddhapichchha Umaswati existed. His disciple was Balakapichchha. Thus, in the lineage of great Acharyas, Acharya Samantabhadra existed."
Inscriptions 105 and 108, which we have already mentioned, say almost the same thing. The only difference is that these two inscriptions mention Gṛddhapichchha Umaswati as the author of the Tattvarthasutra, while inscriptions 47 and 40 do not mention him as the author.
Here, we want to present the lineage based on the aforementioned mentions of the Digambara tradition, the praise inscription found at the end of the Tattvarthabhashya, and the Tapagachchha lineage written by Dharmasagargani. As follows:
