The mention of Siddhasena and others definitively establishes the authorial authenticity of Umaswati. Umaswati refers to himself as 'Vachaka,' which means that the Shvetambara Acharya Umaswati has previously been recognized in a 'foreknowledge' capacity. In the Digambara tradition, he has also been referred to as 'Shrutakevalideshi.' Moreover, Siddhasena considers the commentator and the sutra author to be the same. As stated - "as per the texts stemming from one's own formation" (9.22, p. 253). Accordingly, in the revered teachings of the Arhat concerning the understanding of the Tattvartha, according to the commentary attributed to Umaswati on the Vachaka-knowledge sutra, in the commentary composed by Siddhasena as the eighth chapter forming the basis of the Anagaragaaridharmaprarupaka. The supplement to the seventh chapter of the Tattvartha commentary. For further mentions, refer to (g) Umaswati's Tradition, p. 15. The 120th verse of the Prashamarati text references 'Acharya Paha' as cited in the Nishitha Churni. The author of this churni, Jinadas Mahattara, lived during the eighth century Vikram, as indicated by his reference to the Nandisutra within the churni. Thus, it can be said that Prashamarati is particularly ancient. Therefore, there is no hindrance in attributing this work to the Vachaka.
1. The enumeration of the fourteen predecessors is described in various Agamas. It is also noted that they were knowledgeable about the fifth part of the twelfth limb known as Drishtivada. The traditional belief is that the teachings provided by Bhagwan Mahavira were given first as 'Purvashruta.' There is a conception among Western scholars that the Purvashruta received by Bhagwan Mahavira or his disciples is linked to the tradition of Bhagwan Parshvanath. This Shruta gradually merged into the teachings imparted by Bhagwan Mahavira and was considered part of that. Those who adhered to the twelve vows of Bhagwan Mahavira were knowledgeable about this Purvashruta. Due to the tradition of memorization and other reasons, the Purvashruta gradually diminished, and today it is mostly mentioned nominally as 'Purvagatagatha.' Some texts based on 'Purv' are found.
2. In an inscription number 46 from the Nagar Taluka, he is referred to as 'Shrutakevalideshi,' as follows:
"I bow to Umaswati, the author of the Tattvarthasutra, who is Shrutakevalideshi, the abode of virtues."
