How does Chapter 52 explain the relationship between meditating on Sai's physical form (Saguna) and realizing the formless Self (Nirguna)?

Chapter 52 presents a deep philosophical teaching on the path from form to formlessness. It states that by meditating immensely on Sai's physical or Saguna form, the subtle nature of the Self will eventually manifest as the attachment to the form itself vanishes. The chapter clarifies that the formless Absolute, or Parabrahma, is entirely difficult to understand directly. Therefore, without first entering the Saguna form, the light of the Self cannot be known. Sai Baba showed His own feet, a physical manifestation, and through love, led His devotees mysteriously toward the supreme goal, demonstrating this very principle of realizing the formless through the form.
