The Sanctum of Benediction puzzle isn't the hardest I've come across in Crimson Desert, but it certainly isn't the easiest either. It's plain to see how someone could find this sanctum confusing, especially when one of the parts you recover doesn't seem to fit onto the central device you're trying to repair.
Thankfully, though, it's not anything like the Toward the Nest or the Arboria Castle puzzles, which can both take a long time without outside help. No, you'll have this one done in a jiffy following the steps below. Also, do note that you need to have unlocked the Witch faction questline during Chapter 3's main quest to complete any of the sanctum puzzles.
