Getting to this node is tricky - there is no jumping in Meridian 59, but you can run - run forward and press towards the wall or ledge you are trying to reach. There are 2-3 trick ledges and jumps you must make.

Walk slowly when on the narrow ledges. The node itself is behind a 'fake wall' - when you press on it your character will go through the texture and find yourself in a long hallway leading to the node.

To get to this wall you have to jump from the highest, left-most ledge possible, and press into the south wall while you are falling. Keep pressing as you fall...and you will suddenly find yourself on the path to the node.
