Death is human, not spiritual. The soul never stops living! When you grieve the death of a loved one, remember… you are grieving the absence of their human presence, the absence of their human form; THE SOUL THAT RESIDED IN THAT BODY CONTINUES TO LIVE. The Soul is the essence to ALL , it is light and Energy. It is the Soul that chose THAT human body to bring it to Earth in THAT lifetime.
The material makeup of the body goes back into the soil of the EARTH, the spirit of that being resides on the other side and the SOUL may or may not decide to reincarnate, depending on its accomplishments or objectives.
Take care of the body, it carries the TRUE BEING… the SOUL.
