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

Chapter 52 explains a profound spiritual concept regarding the form (Saguna) and the formless. It states that by meditating immensely on Sai's physical, or Saguna, form, the subtle nature of the Self will eventually manifest as the form itself vanishes. The text clarifies 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 this process, Sai led his faithful devotees mysteriously toward the supreme goal.
