Tell me about the group of devotees from Madras who visited Shirdi.

Chapter 29 describes a group of devotees from Madras (now Chennai) who visited Shirdi. They were travelers on a pilgrimage to Kashi and stopped at Shirdi on the way after hearing of Sai Baba's fame as a great saint. This group had spent the year engaged in devotional singing. The text specifically highlights a smaller group of four within this larger contingent: a man accompanied by his mother-in-law, wife, and daughter. This particular group belonged to the Ramdasi sect and performed devotional singing with great enthusiasm at Shirdi. After taking darshan of Sai Baba and attaining peace, they received eight rupees and eight annas from him.
