Do spirits know when you visit their graves?

Spirit is an energy that animates the body and when that energy leaves the body then, the body dies and the soul leaves the body. One thing you must understand is that death is not the end of life rather, death is a transformation of life from one form to another. The soul of man is incorruptible un-decay and so, its invisible and supernatural. The soul of man lives forever and for this, when you visit someones grave; that’s someone who is yet to reincarnate into physical world, they feel your presence and they see you as well. Depending on what your missions are by deciding to visit their grave, they can send you message either through signs or symbols and in some cases they may take a temporal physical form just for you to see them. Another thing you must understand is that the soul of man is omnipresence and by so, it simply means you can always call out to them anywhere you are and they will hear and send you messages either through dreams, signs, symbols or, taking temporal physical forms for your physical eyes to see them.
