Can you detail the sequence of events that allowed Balabuva Satarkar to perform at Shirdi, starting from the cancellation of his other engagement?

Certainly. Chapter 6 provides a clear sequence of these fortunate events. The chain began when a plague, referred to as Margi, struck the village of Kavthe. Consequently, the annual Ram Navami Kirtan at Siddha-Kavthe, for which Balabuva had an imperial grant, was cancelled. This left him without his usual service and fee but created an opportunity for him to pursue his wish to have Sai Baba's darshan. He then met with the devotee Bhausahab Dixit and expressed this desire. Dixit promised to seek Baba's permission and told him not to worry about travel costs. After Baba gave His approval, Balabuva traveled to Shirdi, where he performed the festival and received a generous payment far exceeding his usual fee.
