What was previously explained as Candavega, powerful time, is covered by days and nights, named Gandharvas and Gandharvis. The body's life-span is gradually reduced by the passage of days and nights, which number 360.
The word parikrantya means "by traveling." The living entity travels on his chariot day and night during a year consisting of 360 (or more) days and nights. Life's progress is taken for the unnecessary labor required to cover these 360 days and nights of life.
