Those who are negative fear death. They do not understand that you cannot die. Negative living clouds the mind and stop it seeing the real truth.
A positive way of living will show you that a being is not just physical. All beings are spirit living in a physical body. The body undergo changes and anything that change must die. So the body of every being must die. The spirit does not undergo change like the body.
It remains constant. When you reach fifty you will feel the same as when you were eighteen. Your body won't feel like eighteen anymore because it has changed. But your spirit will still feel as young as eighteen. So it will forever feel young.
Death comes to the body because it is subjected to change. It cannot affect the spirit in the same way as the body. The spirit is permanent, death
