Besides demonstrating his omniscience, did Sai Baba convey any specific teachings in the story of Laxmichand's visit?

Yes, while the main focus of Laxmichand's story in Chapter 28 is on Sai Baba's omniscience, a specific and practical teaching is also mentioned. The text notes that Laxmichand had taken a loan to make the arrangements for his pilgrimage. Although Baba did not chastise him directly, the narrator of the Satcharitra highlights a key principle. It is explicitly stated in verse 70 of Chapter 28: "Taking loan for a pilgrimage - or going on pilgrimage with debt - Baba does not like indebtedness; this is the main teaching here." This small but important detail shows that while Baba was compassionate and fulfilled desires, he also advocated for a life of financial prudence and disapproved of devotees going into debt, even for pious reasons like a pilgrimage.
