According to Nana Chandorkar's explanation to Kakasaheb Dixit, what is the mechanism by which Sai Baba draws devotees to Himself, and what does this imply about receiving His darshan?

In Chapter 51, Nana Chandorkar explains to Kakasaheb Dixit that Sai Baba has a unique way of drawing His devotees. He shared Baba's constant promise: "No matter how far my person is, even if beyond the seven seas, I tie a string like a sparrow and pull them here immediately." Nana further clarified that this means one cannot be drawn to Him without Baba's own will. This implies that receiving Baba's darshan is not a matter of one's own effort or choice alone; it is a sign that you "belong to Him" and have been specifically chosen and pulled by His grace.
