In the Jain tradition, the scriptures spoken by the Arhats, composed by the Ganadharas, Pratyekabuddhas, or Sthaviras are considered authoritative. Therefore, the credit for the authorship of the Agam scriptures belongs to the great sages. The Anga literature was initiated by the Tirthankaras themselves, and the Ganadharas were the wise men who compiled the sutras. The basis for the composition of the Anga-bahir literature are the Tirthankaras, and the compilers are the Chaturdashapurvi, Dashapurvi, and Pratyekabuddha Acharyas. Acharya Vattekar considered the sutras spoken by the Ganadharas, Pratyekabuddhas, and Abhinna Dashapurvis as authoritative in the Mulachar.
From this perspective, we arrive at the truth that the present available Anga-pravist literature was initiated by Tirthankara Bhagwan Mahavira himself, and the author is his disciple Ganadhara Sudharma. In the Anga-bahir literature, from the perspective of authorship, many Agams were composed by Sthaviras, and many were derived or quoted from the Dvadashaangas.
The Anga literature currently available is the composition of Ganadhara Sudharma, who was a contemporary of Bhagwan Mahavira. Therefore, the time of composition of the present Anga literature is confirmed to be the 6th century BCE. The Anga-bahir literature is not the work of a single person, therefore, they cannot have a single time period. Acharya Shayambhav composed the Dashavaikalika Sutra, while the author of the Prajnapanasutra is Shyamacharya. The author of the Cheda Sutras is Chaturdashapurvi Bhadrabahu, while the author of the Nandi Sutra is Devavachaka. Some modern Western thinkers consider the time of composition of the Jain Agams to be the time of Devarddhigani Kshamasraman, who lived 980 or 993 years after Mahavira's Nirvana. But this belief of theirs is not correct. Devarddhigani compiled the Agams, but the Agams are ancient. Many knowledgeable scholars mix the time of writing with the time of composition, and consider the time of writing of the Agams as the time of composition of the Agams.
Earlier, the Shruta literature was not written. Due to the prohibition of writing, it was being passed down orally. It remained memorized for a long time, which naturally led to changes in the Shruta verses. Devarddhigani Kshamasraman stopped the Shruta stream, which was flowing rapidly towards decline, by putting it into writing. After that, with some exceptions,
