Can you summarize Sai Baba's method of giving and the arrival of the devotees from Madras as described in these verses?

The provided verses from Chapter 29 illustrate two main points: Sai Baba's unpredictable generosity and the arrival of a specific group of devotees. The chapter establishes Baba as a generous saint who frequently distributed money, attracting crowds. However, it emphasizes that his giving was not fixed; he gave to some but not all, based on his own inscrutable will. This is framed as a blessing for the fortunate whose auspicious time had come. The text then provides an example of visitors: a group of four Ramdasi devotees from Madras who, while on a pilgrimage, stopped in Shirdi. They performed devotional singing and, in turn, received eight rupees and eight annas from Baba, showcasing his compassion for pilgrims.
