Enigma

Here is a portal sent through time,
From the future or our past?
Time is a loop,
An eternal ring,
Never ending –
Yet cannot last.
From somewhere beyond,
We may know someday,
Or conversely, never see.
Our limited brain comprehends, not yet,
What our past, and our future have been.
The stones hold the secret
To immortal life,
We have only to find the key.
One day we found the answer
To the puzzle that’s yet to be.
