Who is Sai Baba compared to in his ability to transform devotees?

According to Chapter 4, Sai Baba is referred to as the "Lord of Yoga" and is compared to a philosopher's stone, or "Paris," which turns iron into gold. However, the text states that the actions of a saint like Sai are even more extraordinary. Unlike the stone, which only changes the metal, a saint gives their own form, signifying Self-realization, to their devotees. This comparison highlights Sai Baba's unique and profound power to spiritually transform his followers completely, guiding them toward the state of oneness with Brahman.
