To your Saturn it means that you could feel compulsive behaviors or fears concerning your career and/or discipline and stability. With the Moon, this is the same about your lunar abilities, how you nurture, and view family. You might go overboard in some ways here, but also try to viciously cut or remove in other times.
Knowing that Pluto is in the 1st house, this means the issues from Pluto will mostly stem from concerns and compulsions regarding personal safety, combat, competence, putting yourself first, and so on. Connect this to the placement of your Saturn and Moon to get a more clear picture.
As you advance and also reflect on your own life, plus as you do workings for this, you will begin to see these patterns more readily.
