Okay right now you are facing your cabinet. Turn around and you see three arch ways in front of you. Go straight through the left side one. On the way you can see a door which is open to your left. Enter into that room. Once you enter into the room, Turn around. Walk towards the second archway. Now turn slightly to your left and walk straight till you reach the door to your right and stand between the two stair cases that is on the wooden floor not on the mat. That's the end point.
