## Introduction
Paying homage to the perfected one, the son of the perfected one, the great Mahavira, who has eradicated all karmic impurities, I will explain the eight karmas, their eight karana, and their accompanying udaya and sattva. ||1||
The eight karana are: bandhana, sankramaṇa, udvartana, apavartana, udirana, upasamanā, nidhatti, and nikacchana. ||2||
The first verse pays homage to the perfected one, the son of the perfected one, the great Mahavira, and promises to explain the eight karmas, their eight karana, and their accompanying udaya and sattva. The second verse lists the names of the eight karana, which are described in detail in the Kammapayadī.
The eight karana are: 1. Bandhana-karana, 2. Sankramaṇa-karana, 3. Udvartana-karana, 4. Apavartana-karana, 5. Udirana-karana, 6. Upasamanā-karana, 7. Nidhatti-karana, and 8. Nikacchana-karana.
The nature and other aspects of these eight karana are explained in detail in the Kammapayadī. The Churnikara has also provided a very beautiful explanation of their nature in his Churni. Therefore, at the end of the Tiloyapannatti, he has mentioned the extent of his previous work, along with the extent of the Tiloyapannatti, in the verse quoted above.
At the end of the Nikacchana-karana, the Churnikara has also written the phrase "evam attha vikaranaani samattani," which proves that the Churni of the Kammapayadī was also written by the venerable Yativrishabha.
It should be noted that udaya and sattva are not included among the karana. This is why, at the end of the explanation of the eight karana, the Churnikara has clearly written, "Thus, the nature of the eight karana is complete."
The authors of the Churnis of the Kammapayadī, Sataka, and Sittari are the same.
So far, no mention of any Acharya has been found as the author of the Churni of the Kammapayadī. However, the editors of the Kammapayadī have expressed the possibility, based on tradition, that it was written by Jinadasa Mahātara. This is only a possibility, not a fact, as no evidence has been presented to support it.
Some people believe that the Churni of the Sittari was written by Chandraprabha Mahātara. However, the editors of the Sittari Churni have clearly stated in its introduction that Chandraprabha Mahātara is neither the author of the Sittari nor its Churni. They have clearly stated that Chandraprabha Mahātara mentioned the ancient texts Sataka, Sittari, etc., at the beginning of his Pacasangraha. They have also written that at one point, the opinion of the Sittari Churnikara contradicts that of Chandraprabha Mahātara. This proves that Chandraprabha Mahātara is not the author of the Sittari Churni.
The printed Sataka Churni does not have any editorial statement or introduction, nor does it mention the name of any Acharya as the Churnikara at the beginning or end. However, the printed Sittari Churni contains a photograph of the last page of the Sataka Churni obtained by Shri Shantinathji Bhadar Khambhat, which has the following last line:
"Kritiraacharyashreechandramahattarshitamvarasy. Shatakasy granthasya. Prashastach... . Di 3 Shanau likhiteti."
