There is a key
That opens all doors
There are many doors
However, only one is the path
There are so many paths
But, only one reaches the ridge
There are so many ridges
But only one shows the infinite

Exist, only one infinite
On the skyline of the future
However, the present
Not part of the future

There is a key
That opens only one door
But, it closes as soon as I pass
No one can stop, which I did not start
And no one can't start, which I did not
