How does Chapter 52 explain the importance of Sai's physical form (Saguna) in understanding the formless (Nirguna) reality?

Chapter 52 emphasizes the critical role of Sai Baba's physical, or Saguna, form as a gateway to understanding the formless, or Nirguna, supreme reality. The chapter explains that meditating immensely on Sai's physical form allows the subtle nature of the Self to manifest as the attachment to the form itself vanishes. It directly states that without first entering the Saguna form, the light of the Self cannot be known because the Parabrahma, which is without attributes, is entirely difficult to understand on its own. Through his Saguna form, as mentioned in Chapter 52, Sai showed his feet and used the power of love to lead his faithful devotees toward liberation.
