## Introduction
If the character of the twenty-four Tirthankaras and the Shalakapurushas of their time were to be written, then there would be great benefit to the masses. And if they had decided in their hearts to complete this task, then it would be a great accomplishment. But the work of the commentary on the Siddhanta-granthas, which was started by their Guru, Shri Virsen Swami, remained incomplete after his ascension. A worthy and devoted disciple, who possessed the necessary qualifications, took up the task of completing the work started by his Guru. He completed the work by composing a commentary of 60,000 shlokas, excluding the first part. This task took a lot of your time. After the completion of the commentary on the Siddhanta-granthas, when you got some rest, you took up your long-cherished work and started the composition of that Purana, in which you had promised to depict the characters of sixty-three Shalakapurushas. You had no shortage of words or meanings in your knowledge. Therefore, you were a master in describing any object with great detail. I believe that the readers of the Adipurana will experience this special quality of Shri Jinasen Swami on every step.
## Adipurana
Yes, Adipurana is your previous work. From the beginning to the 42nd Parva, and 3 shlokas of the 43rd Parva were written by your golden pen, when your life ended prematurely and your long-cherished work remained incomplete. There is no way to know when you started and ended the Adipurana, so it cannot be said with certainty that your earthly life ended in a particular Saka Samvat. But let's assume that the composition of the Mahapurana started as soon as the Virseniya commentary was completed. And since Shri Jinasen Swami would have been over 80 years old at that time, the composition would have been done very slowly. It would have taken at least 10 years to compose about 10,000 shlokas. According to this calculation, Jinasen Swami's existence can be accepted till Saka Samvat 770, or if it happened very quickly, then till 765. In this way, it can be assumed that Jinasen Swami benefited the world's distinguished men for 60-65 years.
## Gunabhadracharya
If Gunabhadracharya's age is assumed to be 25 years at the time of Guru Jinasen's death, then it can be assumed that he was born around Saka Samvat 740. But it is difficult to determine when the Uttarapurana was completed and how long Gunabhadracharya lived on earth. Although it is written in the praise of the Uttarapurana that it was completed in Saka Samvat 820. But after a closer study of the praise, it appears that the praise of the Uttarapurana is not uniform, but is divided into two forms. From the first to the twenty-seventh verse, there is one form, and from the twenty-eighth to the forty-second, there is another form. The first form is of Gunabhadra Swami and the second is of his disciple Lokasen. Due to the grace of the scribes, both forms have merged into one. After displaying the glory of the Sangha and the Gurus in the initial 16 shlokas of his praise, Gunabhadra Swami wrote in the twentieth verse that due to the fear of excessive expansion and the request of the extremely short time, I have collected the remaining Mahapurana in brief. After that, in 5-6 shlokas, he described the greatness of the book and said in the final 27th verse that it should be narrated to
