Akalaá¹ ka [<nowiki/>IAST: Akalaá¹ ka] (also known as Akalaá¹ kadeva and Bhatta Akalaá¹ ka) was a Jain logician whose Sanskrit-language works are seen as landmarks in Indian logic. He lived from 720 to 780 C. E. and belonged to the Digambara sect of Jainism. His work Aá¹£á¹Âaà Âatë, a commentary on ÃÂptamëmaá¹Âsa of ÃÂcÃÂrya Samantabhadra deals mainly with Jaina logic. He was a contemporary of RÃÂá¹£á¹Ârakà «ta king Krishna I. He is the author of TattvÃÂrtharÃÂjavÃÂrtika, a commentary on major Jaina text TattvÃÂrtha Sutra. He greatly contributed to the development of the philosophy of AnekÃÂntavÃÂda and is therefore called the "Master of Jain logic".
Akalaá¹ ka flourished in 750 C. E. He was aware of the contents of the Aá¹ gas, although it cannot be said whether they represent an idea rather than a reality for him, and he also seems to have been the first Digambara to have introduced as a valid form of scriptural classification the division into kÃÂlika and utkÃÂlika texts which was also employed by the à ÂvetÃÂmbaras. He is mentioned as a logician and a contemporary of Subhatunga and RÃÂá¹£á¹Ârakà «ta king Krishna I.
The samÃÂdhi of Akalaá¹ ka is located between Thurupammor and Karanthai villages, at a distance of 19 km from Kanchipuram, Tamil Nadu.
