Abhaydevsuri was a renowned Jain acharya and scholar, particularly known for his commentaries on Jain scriptures. According to Jain tradition and texts, the lifespan (āyuṣya) of Abhaydevsuri, like most historical acharyas, is not always precisely recorded in terms of years. Jain texts often focus more on spiritual accomplishments rather than exact chronological details.

However, some sources within the Jain tradition mention that Abhaydevsuri lived for around 74 years. This information is found in certain historical accounts and traditional Jain genealogies of acharyas, but it is important to note that such details may vary slightly depending on the source.

His true significance in Jainism lies in his contributions to Jain philosophy and literature rather than just the length of his lifespan.
