The text says the scene of Baba giving Udi can't be seen now. How does it suggest devotees can still experience it?

Chapter 20 acknowledges that the physical events of that time in Shirdi are in the past. However, it provides a method for devotees to still connect with those moments. The text explicitly states that 'through the power of firm meditation They become visible.' It encourages readers to bring Sai into their meditation, visualize being in Shirdi after the noon Aarti, and behold Him with focused attention. By doing so, one can prostrate with love and continue the connection to those sacred events.
