When The Arahant Dies
When the arahant dies, the physio-mental process comes to an end for lack of the “fuel” needed to keep it going. This fuel is craving, which leads to grasping, which in turn leads to further becoming.
If craving is totally extinguished, there can be no further becoming. When the body dies at the expiration of the life span, no new rebirth takes place.
If there is no rebirth in any plane, then there is no decay, disease, and death; there is no sorrow, lamentation, pain, grief, or despair. This is the end of suffering.
