Can you explain Sai Baba's method of blessing sacred texts and why it was sometimes surprising for the devotees?

Sai Baba's method for blessing sacred texts was often mysterious and tailored to the individual, as detailed in Chapter 27. While devotees expected to have their books returned to them as a blessing, Baba's actions were unpredictable. He knew the state of each devotee's heart. Frequently, after turning a few pages, he would not give the book back to the original owner. Instead, he would hand it to his close devotee, Madhavrao (Shama), instructing him to keep it. This happened with books like Viveksindhu and a copy of the Bhagavata, leaving the hopeful owners empty-handed but teaching a deeper, unspoken lesson. This shows that Baba's grace operated in surprising ways, not always aligning with devotees' expectations but always serving a higher purpose.
