Tell me about the group of devotees from Madras who are mentioned at the beginning of Chapter 29.

Chapter 29 introduces a group of devotees from the Madras region (now Chennai) who were on a pilgrimage to Kashi. Having heard of Sai Baba's fame for being patient, generous, and self-controlled, they made a stop in Shirdi for his darshan. This group, consisting of travelers who had spent the year in devotional singing, belonged to the Ramdasi sect. As described in Chapter 29, they performed their devotional singing with great enthusiasm in Shirdi and stayed near Sai for several days, attaining peace from his darshan. Baba's interaction with them was characteristic of his unpredictable nature; he gave them eight rupees and eight annas, but at other times might give them sweets or nothing at all.
