Illusion or real

In many instances 
With different examples 
It was told 
The world is just a reflection 
Of the real cosmos.
It's a moving train
Boarding and leaving 
Is not your choice.
But you will be 
Thrown out 
When your last
Station will arrive. 
Many accompanied 
Throughout the journey
of your life.
Few were too close 
And few were just known!
But at the destination 
Every one left you
All alone!
One by one!
Left the train
That you thought
As your own home.
Temporary enjoyment 
Will be at end.
No permanent support. 
Life is a droplet 
Disappears anytime 
Out of your control.
Enjoy each moment 
Before the journey ends
Live and let live
Only few moments left!
