I read that Chapter 20 suggests we can still experience past events in Shirdi. How does the chapter recommend doing this?

Indeed, Chapter 20 suggests that even though the events of Baba's life are in the past, they can still be experienced. The text states that through the "power of firm meditation," these past celebrations in Shirdi can become visible. It specifically encourages readers to bring Sai into their meditation, to visualize the scene after the noon Aarti, and to behold him from his toe to his face. By prostrating with love in this meditative state, the chapter suggests one can maintain a connection to the story and to Sai himself.
