Who was the son of Sai Baba's friend that had neglected his family's religious worship?

The son of Sai Baba's friend was Bhagwantrao Kshirsagar. As detailed in Chapter 4, Bhagwantrao's father was a great devotee of Vitthal and a friend of Baba's. After his father passed away, Bhagwantrao neglected the family's spiritual duties; the worship and food offerings (Naivedya) to the household Vitthal idol ceased, and even the annual Shraddha (death anniversary) was skipped. Baba, referring to the father as "a friend of mine," explained that He had pulled Bhagwantrao to Shirdi to remind him of these duties, stating that by neglecting Vitthal, Bhagwantrao was also keeping Baba hungry.
