Describe symbolism in The Five People You Meet in Heaven by Mitch Albom

The Ferris Wheel is a recurring image of every version of Ruby Pier that Eddie visits in Heaven. Other rides come and go, but the Ferris Wheel always defines the park's skyline. Eddie marvels at its sparkling magnificence as a child, he and Marguerite ride the the Ferris wheel on their first date, and Eddie fixes its mechanisms when he gets older. The Ferris wheel is a fixture in Eddie's life that symbolizes the essence of the park; it is a ride that represents joy, solace, romance, and adventure. Eventually, Eddie finds his eternal happiness with Marguerite on the Ferris wheel, connecting it to the cyclical nature of life and death, as well.
