Tell me about the group of devotees from Madras who visited Shirdi as described in Chapter 29.

Chapter 29 narrates the story of a group of devotees from the Madras region (now Chennai) who came to Shirdi for Sai Baba's darshan. These travelers were on a larger pilgrimage to Kashi and had heard of Baba's fame as a great saint. The text mentions that this group belonged to the Ramdasi sect and they performed loving devotional singing with great enthusiasm during their stay. After taking his darshan and attaining peace, they received a specific amount from Baba, who gave them eight rupees and eight annas. Their story serves as an example of the many pilgrims who were drawn to Shirdi by Baba's reputation for compassion and generosity.
