Does the sprit of a dead person return to his/her body after it is buried?
The grave where we put the corpses in, should not be confused with the life of grave and the life of Intermediate Realm. Death is the separation of the physical body from the spirit. It does not return back to the body anymore. The subject in your question is the realization of the dead person that s/he has passed away. It is not the return of the spirit back in to the body that was put in the grave.
