As you may know, if you go down the stairs a little ways on Aes Sedai in Bone Orcahrd, you can shift down from near the portal to the alter room.
Well you can also shift from the roof into two of the four columns located in the corners. (In my opinion purple is the easist, because I have only been able to do the red lamp a few times) Stand beside the lmap and look downward at the floor and shift.
It is a very precise shift so it may take a little work to find. There are more ways to get into the columns.
