Concept of Time

Did you ever think of time and its real nature.

What is time ?

Time is nothing but a change.
See the river is flowing. You say that the river is there since a
long but in reality the water is flowing continuously. That means the
water now flowing is not that same water a minute ago, and after a
minute the water is not the same again.

Think of this.

As this example the time also flows continuously and never returns
back again. While we are taking the 'present' as standard and
referring the future and past from this point, but this 'present'
becomes past, and the future becomes present, and so on changing
continuously like a flowing river.

We are taking a piece of that change and standardizing it as a unit
of time for practical purposes (say an 'hour'). But this may not hold
good when we leave this earth and go to the 'space' far away from
our 'solar system'.

So time is an imaginary, comparative change. In fact there is no such
thing as time. This may be referred to as 'fourth dimension'.
