Can you explain the circumstances that led to Balabuva Satarkar's financial gain from performing at Shirdi?

Balabuva Satarkar traditionally received a fee of 30 rupees as part of a state grant for the Ram Navami festival in Kavthe. As Chapter 6 explains, a plague outbreak one year caused this festival to be canceled, meaning he missed his service and his fee. This led him to Shirdi, where he expressed his desire to perform Kirtan to Dixit. After receiving Baba's approval, Balabuva performed the festival. He was immensely joyful when Baba ordered him to be paid an honorarium of more than one hundred and fifty rupees. Chapter 6 notes that this single festival in Shirdi provided him with the equivalent of five years' income from Kavthe, leaving him feeling grateful to Baba.
