Answer

Jain Agams were not written by one single person.

According to Jain tradition:

• The teachings were given by Bhagwan Mahavir.
• They were first understood and preserved by His chief disciples, called Ganadhars.
• Later, these teachings were passed down orally through Jain Acharyas and monks.
• Eventually, they were compiled in written form by Jain Acharyas.

Explanation

The original source of Jain Agams is the divine preaching of Tirthankar Bhagwan Mahavir. His Ganadhars organized these teachings into scriptural form. Over time, due to loss of memory and changing times, Jain monks preserved and compiled the Agams.

In the Shvetambar tradition, many Agams are accepted as preserved scriptures. In the Digambar tradition, it is believed that the original Agams were gradually lost.

Takeaway

Jain Agams are traditionally understood as the teachings of Bhagwan Mahavir, preserved through the lineage of Ganadhars, Acharyas, and Jain monks.
