Chapter 3 contrasts different spiritual practices and outlines a path from devotional listening to ultimate realization. Can you explain this progression?

Chapter 3 outlines a clear spiritual progression that begins with the simple act of listening. It contrasts this with other efforts like yoga, sacrifice, meditation, and concentration, noting that listening requires no exertion beyond focused attention. The chapter explains that reading or listening with devotion leads to natural meditation on Sai. This, in turn, allows the devotee to see the 'form with attributes' (Sagun), which becomes firmly imprinted on the heart. This experience fosters deep devotion to the Sadguru. As this devotion grows, it naturally leads to detachment from the world and the purification of the intellect, guiding the devotee toward the supreme goal and the regaining of their true, original self.
