How did the darveshis feel after their tiger died? It was their livelihood, right?

Yes, the text highlights the complex emotions of the darveshis. Chapter 31 explains that the tiger was their 'means of livelihood' and their 'family's sustenance,' so when it died, they were naturally 'sad-faced' (verse 158). However, the text also notes that they 'looked pleased' (verse 142). This is because they understood the spiritual significance of the event—that the diseased creature had attained liberation by dying at the feet of a great saint. This duality shows their sadness over their material loss alongside their happiness for the tiger's spiritual gain, as reinforced in verse 157. Their immediate next step was to ask Sai for guidance on the burial.
