Sthananga Sutra (Sanskrit: Sthānāṅgasūtra; Prakrit: Ṭhāṇaṃgasutta)[1] (c. 3rd–4th century BCE)[2] forms part of the first eleven Angas of the Jaina Canon which have survived despite the bad effects of this Hundavasarpini kala as per the Śvetāmbara belief.
This is the reason why, under the leadership of Devardhigani Ksamasramana, the eleven Angas of the Śvetāmbara canon were formalised and reduced to writing.
Importance of Sthānāngasūtra can be gauged from the fact that Vyavahāra Chedasūtra (10, 20-34) mentions that it is suitable to be studied only by those ascetics, who have at least eight years standing in monkhood.
The first sūtra in the Sthānānga goes as follows: sūyam me āusam tenam Bhagavayā evam akkhāyam – "I have heard, o Long-Lived one, that the Venerable (i.e. Mahāvīra) has said thus."
Sthananga Sutra lists the topics which made up the mathematics studied from the time of 2nd century BCE onwards.
