Can you explain the philosophical relationship between the Saguna (form) and the formless Self as presented in Chapter 52?

Chapter 52 presents a deep philosophical concept regarding the path to realizing the formless Self. It states that one must first engage with the Saguna, or the physical form of Sai. The chapter clarifies that without entering the Saguna form, the light of the Self cannot be known, as the attribute-less Parabrahma is exceedingly difficult to grasp directly. By meditating immensely on Sai's physical form, the devotee's focus allows the subtle nature of the Self to manifest as the attachment to the Saguna form eventually vanishes, leading them to the supreme goal.
