**44. Sarvarthasiddhi**
Acharya has called Samayaprabhrut as a part of Arhatpravacana in his commentary on Samayaprabhrut. Generally, both these terms refer to the twelve angas of Jain scriptures. However, when Bhattarak Akalankadev mentions a separate text called Arhatpravacanahriday or Arhatpravacana, and even quotes a verse from it that closely resembles a sutra from Tattvarthasutra, it raises the question: Did such a great text exist, containing the secrets of the entire Jain philosophy, and was its mention mandatory for everyone? Whatever the case, one thing is clear: The author of Tattvarthavartika must have had access to other commentaries on Tattvarthasutra besides the available ones, which were different from Sarvarthasiddhi and Tattvarthabhashya. It is highly likely that he referred to this very commentary in his Tattvarthavartika.
In this context, we have also discussed the commentary of Siddhasena Ganika. We have already mentioned that Siddhasena Ganika's commentary includes many different opinions and references regarding the sutras. A close examination reveals that he had access not only to Sarvarthasiddhi, Tattvarthabhashya, and Tattvarthavartika, but also to many other old and new commentaries on Tattvarthasutra. This is also the opinion of the wise scholar Pandit Sukhlalji, which we have already mentioned.
These references in Sarvarthasiddhi, Tattvarthavartika, and Siddhasena Ganika's commentary suggest the existence of many other small and large commentaries on Tattvarthasutra. The question is, on what basis were these commentaries written? It is clear that those mentioned in Sarvarthasiddhi and Tattvarthavartika were independent. We only need to consider those mentioned by Siddhasena Ganika. It is evident that due to Tattvarthabhashya, the form and meaning of the sutra text are somewhat fixed. Some errors due to the carelessness of scribes are also found in Tattvarthabhashya. However, due to these errors, it is not possible to imagine any variations or interpolations in the entire sutra text in the presence of Tattvarthabhashya. In such a situation, these commentaries must also be considered independent, similar to those mentioned in Sarvarthasiddhi and Tattvarthavartika. The way Siddhasena Ganika mentions other opinions while pointing out differences of opinion also supports this fact.
We cannot say for sure when these commentaries were written or who their authors were. It is highly likely that all or some of them were written before Tattvarthabhashya, and their authors were Svetambara Acharyas. If this assumption, which is more likely to be true, is correct, then we have to say that Tattvarthabhashya was written at a time when many commentaries and annotations on the original Tattvarthasutra were already in circulation, one of which was Sarvarthasiddhi.
**2. Sutra References:**
Generally, commentators refer to previous or subsequent sutras to clarify a topic, provide information, or connect the next sutra. This practice is extensively followed in Sarvarthasiddhi and Tattvarthabhashya. However, while referring to previous or subsequent sutras, these commentaries only mention those sutra texts that they agree with. For example, the author of Sarvarthasiddhi has accepted the 21st sutra of Chapter 1, "Bhavapratyayavadhidevnarakanaam," in this form. Therefore, while writing the introduction to the first sutra of Chapter 4, he mentions this sutra in the same form. Similarly, the author of Tattvarthabhashya has accepted this sutra as "Bhavapratyayavadhinarakavevaanaam."
