According to Chapter 52, what is the relationship between Sai Baba's physical form (Saguna) and the formless Self?

Chapter 52 delves into the profound relationship between meditating on Sai's physical form and realizing the formless Self. It teaches that the Parabrahma, which is without attributes, is incredibly difficult to comprehend directly. Therefore, one must first enter the Saguna form, or the physical manifestation of the divine. As stated in Chapter 52, by meditating intensely on Sai's physical form, the devotee can eventually perceive the subtle nature of the Self as the perception of the form (Saguna) vanishes. This process is how Baba mysteriously led his faithful devotees toward the supreme goal of liberation.
