According to Chapter 52, what is the importance of Sai's physical form (Saguna) in spiritual practice?

Chapter 52 highlights the critical role of Sai Baba's physical or Saguna form in a devotee's spiritual journey. It explains that meditating intensely on Sai's physical form is the very means by which the subtle, formless nature of the Self can be realized, as the attachment to the form eventually vanishes. The chapter posits that without first entering the Saguna form, the light of the true Self cannot be known, because the formless Absolute, or Parabrahma, is entirely difficult to understand directly. Through the power of love, Sai showed His own feet and used His physical presence to mysteriously guide His faithful devotees toward liberation.
