What are the specific benefits and spiritual progression that result from chanting Sai's name as detailed in Chapter 46?

According to Chapter 46, chanting Sai Baba's name is an easy and powerful remedy for true devotees. The practice is said to wash away sins, destroy the qualities of 'Rajas' (passion) and 'Tamas' (ignorance), and fulfill the desires of those who have them. For the desireless, it bestows the bliss of the self. The chapter outlines a clear spiritual progression: chanting leads to an increase in 'Sattva' (purity), which fosters a righteous disposition. This, in turn, brings about detachment from worldly subjects and ultimately leads to the manifestation of self-knowledge.
