Orient the pillars to complete the image behind them to power the Ruins Teleporter in Amnesia: Rebirth.
Once you enter the gigantic Amnesia: Rebirth Ruins Chamber, Tasi will notice the three giant pillars with runes on either side. In the center of the room is another runic board puzzle, although this time around you will first need to understand the sequence the pillars should be in before you crack the code. This can be done in two ways: the painful "find the note with the clue" method, or the "use this guide to avoid the scary monster" strategy.
If you want the full Amnesia: Rebirth experience, head up the stairs and enter the side chamber to look for a note that indicates how Tasi can find the solution. Just, you know, dodge the ghoul lurking in the joint. There is a note at the back of the room near a corpse with the answer, mentioning the image behind the pillars. Once you have that, head back to the main ruin chamber to solve the teleporter puzzle.
Whether you've braved the beast or jumped straight to this paragraph, you'll now need to rotate the pillars manually. There are three in total, although the first pillar on the left is locked in place. The other two can be moved, but before you do anything else, take a first step in front of the runic panel. Look ahead and focus on the picture of the pillars. Notice all the lines, and how the pillars also have lines?
You have to make a complete circuit between the three pillars, and since the first one cannot be moved, it will serve as a reference. Rotate the other two pillars until the loop and runes on the pillars start to glow, or reference my Amnesia: Rebirth screenshot below if you'd rather go the easy route.
Once the pillars of the ruins are oriented correctly, return to the rune panel to move the red bar to the correct combination. This time you will need to rotate the panel to line up the right combination from left to right, then move the bar on it. Once you're done, press the button at the top of the panel to power up the teleporter in the ruins. Congratulations, but your journey to Amnesia: Rebirth is far from over. You always have to go back to the top. Have fun: there is no unconditional puzzle between you and the teleporter. Just good old scares. Enjoy!
