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

Chapter 29 narrates the story of a group of devotees from the Madras (now Chennai) region who visited Shirdi. This group of travelers, who belonged to the Ramdasi sect, had spent a year engaged in devotional singing and their fame had spread. While on a pilgrimage to Kashi, they made a stop at Shirdi to have the darshan of Sai Baba. After taking his darshan, they attained peace and stayed for several days, performing loving devotional singing with great enthusiasm. The chapter mentions that Baba, pleased with them, gave them a sum of eight rupees and eight annas.
