emmm dont remember .... im near the cave, wait a second, and i see if i get the order of the pilars.
Ok, you enter the cave, go to down the stairs to the right. yo have 3 ways, right to a lava lake, center to a pilar, left down a lvl. go center (down, then right...) smash that pilar, go up again, you can cross the lake. (if you do it right, when you smash the pilar a messenge will say that the lava run thru it)
cross the lake, go up, and another lake, you will need to smash one of the three pilars in the first lvl. and then that. explore, see if there is another lake, an just serch for a pilar in the level down it.
