The Secret door

How could this one door be?
A secret door to paradise.

No different than the rest,
Yet all the more different.

In the maze,
Walking in confusion,
Getting lost,
Stumbling across this.

Paradise beyond surely,
Yet unable to step further.

Surely can't be lead to the door,
And stopped from stepping any further.

There must be a purpose,
There must be a reason,
Behind stumbling across this,
It can't be all for nothing.
