Can you elaborate on the spiritual progression from chanting to self-knowledge as detailed in Chapter 46?

Chapter 46 outlines a clear spiritual pathway that begins with the practice of constantly chanting Sai's name. According to the text, this initial step destroys sins and eradicates the qualities of 'Rajas' (passion) and 'Tamas' (ignorance). As these diminish, 'Sattva' (purity) gradually increases, leading to the accumulation of 'Dharma' (righteousness). Once this righteous disposition is awakened, detachment from worldly objects is said to come running behind it. This detachment then allows for the instant manifestation of self-knowledge, which is gained along with 'Viveka' (discrimination). This entire process culminates in the devotee's focus remaining on their true self at the Guru's feet.
