How does one diplay only the referenced entities associated with specific node in a view block?
If you use Drupal 7, you must go to: Structure > Views > (Choose the view you want to customize).
There you will find a section "Filter Criteria" if nothing exists press add on the right and add your criteria. You select it and continue with the customization, each element has different customization.

On the bottom you usually see the result, if nothing is shown, then this does not necessarily mean that you made a mistake (I had that problem once). Don't forget to save.
