In some religions, paradise is considered the ultimate destination, but in general, it's any place that is ideal and free from worry. Eden, Shangri-la, or even the corner nail salon — each might represent paradise to someone.
Paradise comes from the Greek paradeisos meaning "park, paradise, Garden of Eden." The Garden of Eden was a paradise free from all worries until Eve ate the apple that broke the dream. Often when you see advertisements for tourism in the Caribbean, a sense of paradise is evoked by the beautiful images and carefree descriptions.
