The Citadel of Chaos

The door opens into a short passageway which is paved with small stones.
A short distance further on, an ornately carved door marks the end of the passageway.
But just before the door, a side passage leads off to the left.
You approach the door, listening for any signs of life inside.
As your hand touches the handle, a voice says:
'Do not knock; just enter!' from inside.

Will you enter the room as instructed ?

or will you decide against this room and take the passage leading off to the left ?
