What is the spiritual path to self-knowledge outlined in Chapter 46, and what are its stages?

Chapter 46 details a clear spiritual path that begins with complete surrender of one's body, speech, and mind at Sai's feet. The next step is the constant chanting of his name, which is described as an easy remedy that washes away sins. This practice, as mentioned in Chapter 46, leads to the destruction of the qualities of 'Rajas' (passion) and 'Tamas' (ignorance) and the gradual increase of 'Sattva' (purity). This accumulation of purity awakens a righteous disposition (Dharma), which in turn brings about detachment from worldly concerns. Finally, this detachment allows self-knowledge to manifest instantly, leading to a state of being focused on one's true self at the Guru's feet.
