When a loved one dies, the pain of those left behind can be eased if they have an acceptable idea of death, from the perception of the soul.
Plato said; "Once free of the body, the soul is able to see truth clearly because it is more pure than before and recalls the pure ideas which it knew before"
Survivors must learn to function again without the physical presence of the person they loved by trusting the departed soul is still with them. Acceptance of loss comes one day at a time. Healing is a progression of mental steps that begins with having faith you are not truly alone.
We have a life contract we made in advance with the departed, and in order to complete this contract it is necessary to rejoin the rest of humanity as an active participant. We will see our love again soon enough.
Death only exchanges one reality for another in the long continuum of existence.
