Past, Present or Future - Which is Real?!

We refer to the 'PRESENT' as a time slot that is real and existing.

I think that is somewhat misleading because the 'Present' is just a door through which the 'FUTURE' passes through to the 'PAST'. It is just a transitory stage during which that which is 'to be' becomes that which 'had been'.

What then is 'REALITY'? We normally consider the 'present' as real, the future and past being treated as something 'unreal'. If the 'present' is momentary, so's 'reality'; something that manifests itself for a fleeting moment and disappears into the 'past'.

Perhaps, 'FUTURE' is the reality that manifests itself to us for a moment before passing into the 'past'!!

A 'period' or a 'time slot' should have a 'finite duration' as well as a 'beginning and an end'. The future and the past have neither a beginning nor an end while the present is momentary and lacks a finite duration. May be, the whole concept of 'Past, Present & Future' as well as of 'Time & Reality' are just creations of the fertile human mind!!
