Can you describe the incident involving Kaka Mahajani and the two copies of the holy book Bhagavata?

Yes, Chapter 27 recounts a notable event with Kaka Mahajani and two copies of the Bhagavata. Kaka Mahajani first arrived in Shirdi with a copy of the book. Shama (Madhavrao) picked it up and brought it to the Masjid. Baba took the book, looked at it, and then gave it to Shama, saying, "Since I have given this to you, keep it in your collection." Later, Kaka Mahajani came to Shirdi again, this time bringing another Bhagavata which he placed in Sai's hands. Baba blessed this second book, returned it to Kaka, and ordered him to "Apply your heart to it," assuring him it would be a dear friend. This demonstrates Baba's unique method of blessing devotees and ensuring sacred texts were valued and preserved.
