Who was Laxmichand, and how is his story introduced in this chapter?

Chapter 28 introduces a devotee named Laxmichand as an example of Sai Baba's power to draw people to him. At the time, Laxmichand was working as a trustworthy and obedient munshi (clerk) for the Ralli Brothers, a firm of Greek merchants with a shop in Mumbai. The chapter mentions his prior employment in the railways department and at the Venkatesh Printing Press. He is described as one of Baba's "pious chicks," fulfilling Baba's promise to bring his people to him from distant lands, just as one would pull a sparrow's chick by a string tied to its feet.
