Answer

The Āchārāṅga Sūtra is one of the most important and oldest scriptures of the Śvetāmbara Jain canon. It mainly teaches the conduct, discipline, non-violence, restraint, and spiritual life of Jain monks.

Traditionally, it is not considered the work of one ordinary “author.” In Jain tradition, the teachings come from Bhagavān Mahāvīra, were preserved by his disciples, especially the Gaṇadharas, and later transmitted through the Jain monastic lineage.

Who Wrote the Āchārāṅga Sūtra?

According to Jain tradition:

• The teachings originate from Bhagavān Mahāvīra.
• They were first systematized by his chief disciples, known as Gaṇadharas.
• The scripture was preserved orally for generations by Jain monks.
• In the Śvetāmbara tradition, the Āgamas were later compiled and preserved in canonical form through the monastic councils.

So, it is more accurate to say:

The Āchārāṅga Sūtra is a canonical Jain scripture based on the teachings of Bhagavān Mahāvīra, preserved by the Jain monastic tradition, rather than a book written by a single individual author.

General Summary

The Āchārāṅga Sūtra focuses mainly on:

• Saṃyama — self-restraint
• Tapas — austerity
• Renunciation — giving up attachment
• Carefulness in walking, speaking, eating, and living
• Endurance of hardships by monks
• The life and spiritual discipline of Bhagavān Mahāvīra
