What was the underlying motivation for Sai Baba's actions, such as his fondness for lighting lamps?

The source material clarifies that Sai Baba's actions were not driven by personal desires or whims. Although he was described as being 'fond of' lighting many lamps, Chapter 0 explains that this is a worldly term and that for Maharaj, 'no whims remained.' The true motive behind his actions was a deeper one: 'doing good for the people.' This principle is clearly demonstrated by the lamp-lighting incident. His persistence in lighting them, even when denied oil, led to a miracle that ultimately dispelled the villagers' delusion and strengthened their faith. Thus, as Chapter 0 indicates, his activities were purposeful acts intended for the spiritual and material welfare of others.
