Samavāyāṅga Sūtra (c. 3rd-4th century BCE)^[1] is the 4th amongst the 12Angas of theJaina canon. Thesutra is believed to have been composed byGaṇadharaSudharmasvāmī. This text contains the essence ofJain religion, defined and catalogued systematically. Written c. 300 BCE, it is a part of the collection of texts containing LordMahavira’s teachings, collectively termed asAgama Sutras. Additionally, it includes one of the earliest references to the Indian writing tradition.^[2]

Samavāyāṅga Sūtra contains elements of mathematics and astronomy. One of the interesting aspects of this text is its portrayal of Monasticism and spirituality in the terms of numerology.

Mathematics - The Samavāyāṅga Sūtra seems to be in continuation of theSthananga Sutra and follows the numeric method of describing substances from 1 to 1 billion.

Astronomy– It contains discussion onMount Meru, the jyotiścakra, the Jambudvīpa, the measurements used in the Jaina canon, the Jaina Loka, the different types of Earth, the 7 Hells, the increase in water levels in the Lavana ocean and like.

It also gives information on the subject matter of the 14Pūrva and the 12th Aṅga,Drstivada. Being one of the oldest and most referred texts, it forms the backbone of the Jaina literature. There is a description of the life-span of the Gods in the Samavāyāṅga Sūtra. There is also a mention of the days of their inhalation and exhalation. It further defines and catalogues the main substances of the Jain religion from a different perspective than theSthānaṅga Sūtra. Furthermore, it contains references to the Damili script, an earlyTamil script known asTamili.
