Can you explain the 'sparrow with a string' analogy mentioned in Chapter 28 and how it applies to the devotee Laxmichand?

Chapter 28 recounts a famous saying of Sai Baba: "My person may be in distant lands, may be thousands of miles away, I will bring him like a sparrow's chick, binding a string to his feet." This powerful analogy illustrates Baba's divine will and ability to draw His chosen devotees to Him, regardless of physical distance or circumstance. The chapter explicitly states that many people had heard Baba say this and had experienced its truth. The narrative then introduces a devotee named Laxmichand, who worked as a munshi in Mumbai, and describes him as one such "pious chick" who belonged to Baba and was ultimately drawn to Shirdi, demonstrating the divine play described in the analogy.
