How does Chapter 52 describe the relationship between meditating on Sai's form and understanding the formless Absolute (Parabrahma)?

Chapter 52 presents a clear spiritual progression, explaining that meditating on Sai's physical form, the Saguna, is an essential first step toward understanding the formless Self. It suggests that "Without entering the Saguna form, the light of the Self cannot be known." The text clarifies that as one meditates immensely on Sai's physical form, the subtle nature of the Self will manifest as the Saguna form itself vanishes from the devotee's consciousness. This is because the Parabrahma, which is without attributes, is described as being "entirely difficult to understand" directly. Therefore, as Chapter 52 instructs, embracing the manifest form of the Guru is the pathway to realizing the unmanifest Absolute.
