Finished my Shatter Effect of a Background Layer, However Cannot View it ALONG WITH the Rest of Proj

-I understand double-clicking on main comp (from shatter effected layer) will return me to the main project, yet it is without this layer shown!
-I also understand that double clicking on this shatter effected layer (from the main comp) will bring me back to this screen, without view of any other layers.
-I have watched tutorials and reads a bunch already, but
How Does One Review BOTH in the Totality of the Whole Composition?
Thank you to however actually knows this answer!
