It marks the end of life and can occur due to various reasons, including natural causes, illness, or accidents. The process of dying can involve physical, emotional, and spiritual aspects, affecting both the individual and their loved ones. In many cultures, death is viewed as a significant transition, often leading to beliefs about an afterlife or reincarnation.
