I meant it different than that. But I will help now.

Hrmm...

When you first enter, go down all the way to that potion. Now, go back up and turn right. Keep going until you see an open "room" with a chest in it. This contains "cure" magic. Get out of there and make a right, go down when you hit that wall all the way into the next chamber. Go right until you hit the wall. Go down again and you'll reach the next chamber.
Go down, when you get to that intersection, go up, keep following the trail and you'll reach Djinn. That's the best I can explain it without actually using your DS to do it for you.
