Why is the town of Shirdi equated with major pilgrimage sites like Kashi and Pandharpur?

Chapter 4 explains that Shirdi's holiness stems directly from Sai Baba's presence, which made the location glorious, similar to how saints like Eknath and Dnyandev sanctified their respective towns. For devotees, Shirdi became the ultimate pilgrimage destination, encompassing the sanctity of all others. The text explicitly states, "Shirdi is our Pandharpur, Shirdi is Jagannath and Dwarka. Shirdi is Gaya, Kashi, Vishweshwar, and Shirdi is also Rameshwar." Association with Sai in Shirdi was considered an easy spiritual path, where his mere sight (Darshan) was a form of Yoga. The very stones and grass were deemed blessed for having touched his feet, elevating the entire town to a place of supreme spiritual significance.
