Chapter 28 introduces Laxmichand as a trustworthy and obedient clerk, or munshi, working for the Ralli Brothers, who were Greek merchants. His story serves as a prime example of Baba's famous saying, also quoted in this chapter: "My person may be in distant lands... I will bring him like a sparrow's chick, binding a string to his feet."
