How did Sai Baba manage the spiritual instruction of devotees, even those who were far away?

Chapter 18 highlights Sai Baba's profound skill in bestowing grace and instructing devotees in various ways. It explains that whether a devotee was near or in a distant land, Baba was always close within them. Even while physically sitting in the Masjid, He could assign a task to someone, give them His own power, and ensure the work was completed. This illustrates that Baba's guidance was not limited by physical proximity, as He worked through others and directly within the hearts of His followers to facilitate their spiritual progress and welfare.
