Describe how the text compares Sai Baba to other great saints, like Ramdas, and what makes saints in general so extraordinary.

The text draws several comparisons between Sai Baba and other great saints. As Chapter 4 explains, just as the great saint Ramdas appeared on the banks of the Krishna for the world's upliftment, Sai, the "Lord of Yoga," appeared on the Godavari for a similar purpose. The text also likens Sai Nath's presence in Shirdi to that of Damaji in Mangalwedha and Narasimha Saraswati in Wadi. More broadly, Chapter 4 describes saints as being even more extraordinary than a philosopher's stone. While a philosopher's stone can turn iron into gold, saints are greater because they can give their own form, or Self-realization, to their devotees, which is considered a far more profound transformation.
