20. Time in the Indus culture
Time in the Indus culture is displayed in a similar way as is described in Jain scriptures as one of the six eternal components of nature, i.e. the cycle of practicality, the bhava chakra: a wheel rotating on the two rods of day and night 
as is shown in the Indus seals. Because time is unidirectional, it progresses or moves in one direction only, and runs with snake-like curves, known as the utsarpini of increasing happiness, or upwards-moving-snake time curve and awasarpini of increasing unhappiness or downwards-moving-snake time curve respectively. This is also seen on the Indus. seals. Each
utsarpini and awasarpini wave has six segments hence each chakra has six segments, yet it can be shown either as a snake (called ‘worm’ by many scholars) or as a double loop, a single loop, or even as a sand clock presenting the utsarpini and the awasarpini time curves on the Indus finds or seals. As the name implies, applicative time is
As a snake (worm) As double loop As single loop
As sand clock
depicted as a snake, while the time as an eternal component of nature is known as kaal or kala. It is eternal and manifests itself cyclic, hence 
it is depicted as a chakra or wheel, and is located in the smallest indivisible unit of space or pradesh as a bead and known as a samaya or smallest time unit filling the whole universe and rotating continuously at its own place. These concepts appear in theIndus texts also.
