The Two

There are Gates meant to keep out
and
There are Gates meant to keep in.

Paths that lead toward
and
Paths that lead away.

Stairs for ascent
and
Stairs for descent.

Doors for one to go in
and
Doors for one to go out.

There are Ways that lead to the means
and 
There are Ways that lead to the ends.

The trick is knowing
which one you're on
or which side.
