What is the relationship between a devotee's offering and the blessings they receive from Sai Baba, based on the story of the Madras group?

The story of the Madras pilgrims in Chapter 29 illustrates that the material value of an offering is less important than the spiritual blessings received. A group offered a bafri of two rupees, and in return, they received abundant blessings from Sai Baba. He assured them, "Allah Malik bahut dega (Allah, the Master, will give much)" and "Allah tumhara achha karega (Allah will do good for you)." These blessings proved far more valuable than money, ensuring their pilgrimage was completed safely and without any hardship, demonstrating that Sai's grace far outweighs any material gift.
