Describe the background of the performer Balabuva Satarkar, known as the 'Modern Tukaram', before his significant visit to Shirdi.

Chapter 6 provides details on Balabuva Satarkar, who was famously known as the 'Modern Tukaram' due to his skill in singing Bhajans. He was a Haridas who originally came from Satara but was living in Parel, Mumbai, at the time of these events. His life involved a significant annual duty at a holy place called Siddha-Kavthe in the Satara district, where he had a grant to perform the Ram Navami Kirtan. This service was supported by an imperial decree which allocated funds for the festival, including a thirty-rupee fee for the Buva. Even before circumstances forced his hand, he held a personal desire to have Sai Baba's Darshan.
