The concept of the six ārās is mentioned in the Samvayanga Sutra (Samavāyāṅga Sūtra), where the six ārās of the descending time cycle and the six ārās of the ascending time cycle are described. ( jainqq.org)
Explanation
In Jain cosmology, the time cycle is divided into Avasarpini and Utsarpini, and each of these has six ārās or ages. The Samvayanga Sutra gives this classification clearly. ( jainqq.org)
