Can you detail the practice of devotees offering books to Sai Baba and what would happen?

Devotees had a practice of bringing books from shops to offer to Sai Baba, hoping to receive them back as a blessed object, or 'prasad'. As described in Chapter 27, they believed that reading a book blessed by Baba would lead to the acquisition of merit and supreme welfare. Devotees would often take Madhavrao (Shama) along to act as an intermediary. They would give the book to Baba, who would turn the pages. However, in a surprising turn, Baba would often not return the book to the original owner. Instead, he would give it to Shama to keep, demonstrating his wonderfully unpredictable nature in granting grace.
