Avasarpiṇī
Avasarpiṇī is the descending half of the cosmic time cycle in Jainism and the one in which the world is said to be at present. According to Jain texts the Avasarpiṇī is marked by a decline in goodness and religion. The ascending half of the cycle is called utsarpiṇī, which is marked by the ascent of goodness and religion. Overview Jaina cosmology divides the worldly cycle of time (kalpakāla) in two parts or half-cycles (kāla) – ascending (utsarpiṇī) and descending (avasarpiṇī) – each consisting of 10 x 1 crore x 1 crore addhāsāgaropama (10 kotikotī sāgaropama). Thus, one cycle of time (kalpakāla) gets over in 20 kotikotī sāgaropama. During the ascending period (utsarpiṇī) of the half-cycle (kāla), in the regions of Bharata and Airāvata, there is the all-round increase in age, strength, stature and happiness of the living beings, while during the descending period (avasarpiṇī) of the half-cycle, there is the all-round deterioration. Each half-cycle is further divided into six periods of time. The periods in the descending (avasarpiṇī) half-cycle are termed as: susamā-susamā, of 4 kotikotī sāgaropama susamā, of 3 kotikotī sāgaropama susamā-dusamā, of 2 kotikotī sāgaropama dusamā-susamā, of 1 kotikotī sāgaropama minus 42,000 years dusamā, of 21,000 years
