Can you explain Baba's "sparrow's chick" analogy and how it relates to the story of Laxmichand?

Chapter 28 explains Sai Baba's method of attracting devotees through his famous analogy: "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 illustrates Baba's divine power to draw his chosen ones to him, regardless of distance or circumstance. The chapter presents the story of Laxmichand as a prime example of this divine play. Laxmichand, a trustworthy clerk working in Mumbai, is described as one of the "pious chicks" who belonged to Baba. According to the text, it is when the "accumulated karma of many births rises up" that one attains the company of saints, and Laxmichand was one such soul drawn to Shirdi by Baba's invisible string.
