How did Sai Baba's presence in Shirdi serve the purpose of uplifting the world, as described in this chapter?

Chapter 4 explains that Sai Baba's appearance in Shirdi was an act of divine purpose for the world's upliftment. It draws a parallel to the great saint Ramdas, who left the Godavari to appear on the banks of the Krishna for a similar mission. In the same vein, Sai, referred to as a "Lord of Yoga," is described as the "great merit of Shirdi" who appeared on the Godavari for the sake of uplifting humanity. His presence transformed Shirdi into a holy place, similar to how other saints consecrated locations like Mangalwedha, Sajjangad, and Wadi, making it a focal point for spiritual seekers.
