In order to do this task, after passing the first stage in 3 chapters and going down;
1. - Open the doors by placing the stones,
   
2. Put the character where the first stone is and place the stone closest to the doors between the spirit and the doors,
   
3. Then revive the character and bring the stone from the door to where the gap is and jump up.

You can also do the "Who needs this anyway?" task again at the beginning of the chapter by placing the first stone in the middle door after taking the first stone at the beginning of the 3rd chapter.
