Perhaps they are not stars, but rather openings in heaven where the love of our lost ones pours through and shines down upon us to let us know they are happy.
As Jacob Boehme puts it, "I am a string in the concert of God’s joy."... We need to experience our own personal aliveness as part of that greater cosmic aliveness...When I become "a string in the concert of God’s joy," I am "sounded through" by the music, and in that sounding, in harmonic resonance with all the other instruments, is revealed both my irreplaceable uniqueness and my inescapable belonging.
