Why were the darveshis both sad and pleased when their tiger died in front of Baba?

According to Chapter 31, the darveshis had conflicting emotions. On one hand, they were 'sad-faced' because the tiger was their primary 'means of livelihood' and their 'family's sustenance.' Its death meant a loss of income. However, they were also pleased because they recognized the spiritual fortune that had befallen the animal. The text in Chapter 31 notes that they were happy that the 'diseased one, near death,' had attained liberation by expiring at the feet of a saint like Sai, which they understood to be an incredibly meritorious end.
