Every time cycle is further sub-divided in two equal halves.
The first half is the progressive cycle or ascending order, called Utsarpini. The other half is the regressive cycle or the descending order, called Avasarpini. Every Utsarpini and Avasarpini is divided into six unequal periods called r s. During the Utsarpini half cycle, progress, development, happiness, strength, age, body, religious trends, etc., go from the worst conditions to the best. During the Avasarpini half cycle, progress, development, happiness, strength, age, body, religious trends, etc. go from the best conditions to the worst.
