What is the significance of meditating on Sai's physical (Saguna) form as described in Chapter 52?

Chapter 52 highlights the importance of the Saguna, or the form with attributes, as a crucial step in spiritual practice. It states that the light of the Self cannot be known without first engaging with the Saguna form, because the attributeless Parabrahma is exceedingly difficult to comprehend directly. The chapter teaches that by meditating immensely on Sai's physical form, the subtle nature of the Self will eventually manifest as the Saguna form itself vanishes. This process is how Sai Baba mysteriously led His faithful devotees toward the supreme goal of liberation while they were still in their bodies.
