The text mentions that past events in Shirdi can still be seen. How does Chapter 20 suggest one can achieve this?

Chapter 20 explains that although the past celebrations and scenes with Sai Baba in Shirdi cannot be seen in the present, they can become visible through the 'power of firm meditation.' The text encourages devotees to bring Sai into their meditation, specifically suggesting they visualize the scene after the noon Aarti. By meditating in this way and beholding him from 'toe to his face,' one can connect with those past events and experience his presence, as described in the chapter.
