Besides demonstrating His omniscience, what other specific teaching is mentioned in the story of Laxmichand's pilgrimage to Shirdi?

In the narrative of Laxmichand's visit to Shirdi, a specific and practical teaching from Sai Baba is highlighted. The source material from Chapter 28 explicitly states that Baba does not approve of taking on debt for spiritual activities. The text says, 'Taking loan for a pilgrimage - or going on pilgrimage with debt - Baba does not like indebtedness; this is the main teaching here.' This practical advice is mentioned in the context of the arrangements made for the pilgrimage, indicating that while spiritual devotion is important, it should be practiced with financial prudence and without incurring debt. This shows that Baba's guidance extended to both the spiritual and worldly affairs of His devotees.
