There is a time which has been made by the God. It is like that river which always flow with same constancy, which never dries up, in which there are no ripples, no high or low tides. There does exist any moon which can cause it to have tides. In fact nothing can change its tranquility. It flows unmindful. It never ceases to flow. There is nary a change even an iota. So this is the time of the God.
This is the basic time. If we represent it in the Cartesian two dimensional space. It shall be represented by a straight line wavering not even by microns.
But for us humans, time has very different meaning. It has tides, floods or droughts. It even flows at different rates. This is like sinusoidal wave overlaying the basic line of time.When we are having happiness and enjoyment, time seems to flying fast. On the other hand, when we are passing through rough patches, time seems to stand still.
The best human is that who tries to minimize these troughs and crests from the curve. More we are nearer the basic time line, more we are closer to nature, or God or call it whatever.
