## Sarvarthasiddhi
It is well-known that the author of Sarvarthasiddhi is the same person who wrote it. Therefore, there is a doubt that he might have only mentioned the sutras of the Jainendra grammar he created in Sarvarthasiddhi. This question was before us during the time of the editor of Sarvarthasiddhi, and from this perspective, we also looked at Sarvarthasiddhi. However, considering the sutras mentioned in it, we have reached the conclusion that there was no such insistence on his part to only quote the sutras of the Jainendra grammar he created. Although the mention of sutras in Sarvarthasiddhi is very rare, the way they are mentioned in two or three places shows that both Panini and Jainendra grammars were used in this work. For example:
Firstly, we see the mention of two sutras in the commentary of Sarvarthasiddhi on chapter 4, sutra 19. The first one is 'tad asminn asti iti', and the second one is 'tasya nivasah'. The first sutra is available in Panini's grammar as 'tasminn asti iti des tamnami 4 267', and in Jainendra grammar as 'tavasminn asti iti desah khi 4, 1, 14'. Therefore, it is difficult to say whether Acharya Pujyapada has relied on Panini's sutra or Jainendra's sutra here. The second sutra is available in Panini's grammar as 'tasya nivasah 4, 2, 69', and in Jainendra grammar as 'tasya nivasadur bhayoh 3, 2, 19'. It is clear that Acharya Pujyapada has mentioned the sutra of Panini's grammar here.
In the commentary of Sarvarthasiddhi on chapter 5, sutra 1, the sutra 'visheshanam visheshyen iti' is mentioned. Jainendra grammar has marked this in the same form at number 1, 3, 52, and in its place, the sutra of Panini's grammar is 'visheshanam visheshyen bahulam'. It is clear that Acharya Pujyapada has mentioned the sutra of his own grammar here.
This was the discussion about the sutras. Now, look at another evidence - in the commentary of chapter 5, sutra 4, Acharya Pujyapada has mentioned the word 'mevetyah'. But there is neither any sutra in Jainendra grammar to prove the word 'nitya' nor any indication of the 'ty' suffix. There is the 'y' suffix in place of the 'ty' suffix. This shows that Acharya Pujyapada has written this sentence keeping in mind Katyayana's Varttika 'tyabane dhruva iti vaktavyam 4, 2, 104'. Acharya Abhayanandi has definitely created this Varttika 'vam iti vaktavyam' in his Vritti. But it is a later composition. Still, the said word is definitely controversial.
In the light of these facts, it becomes clear that Acharya Pujyapada has used Panini's grammar as well as Jainendra grammar in his Sarvarthasiddhi commentary, and it becomes clear that he wrote the Sarvarthasiddhi commentary only after the creation of Jainendra grammar. In the commentary of Sarvarthasiddhi on chapter 10, sutra 4, Acharya Pujyapada has used the term 'ka' for the fifth case ending. Acharya Pujyapada has defined seven case endings in his Jainendra grammar by adding 'ma' to the consonant letters of the word 'vibhakti' and 'v' to the vowel - ba, ipu, bha, ap, ka, ta, ipu. According to this, 'ka' is the indication of the fifth case ending. This is also an evidence that indicates that Jainendra grammar was created before Sarvarthasiddhi was written.
Katyayana wrote Varttikas on the grammar sutras of Panini. In the commentary of Sarvarthasiddhi on chapter 7, sutra 16, Acharya Pujyapada has quoted his Varttika 'ashvavrishabhayo maithuneshchaayam' by calling it 'shastra'. This is the first Varttika of Katyayana on Panini's 7, 1, 51.
Patanjali Mahabhashya - Patanjali Rishi has become a great scholar in the Vedic tradition. The Patanjali Mahabhashya available on Panini's grammar at this time is his immortal work. He is also the author of Yogadarshan. This is clear from it.
