How does this chapter explain the role of meditating on Sai's physical form (Saguna) in achieving spiritual understanding?

Chapter 52 explains that meditating on Sai's physical, or Saguna, form is a crucial step toward spiritual realization. The text suggests that without first entering the Saguna form, one cannot know the light of the Self, as the Parabrahma, which is without attributes, is otherwise entirely difficult to understand. It is through immense meditation on Sai's physical form that the subtle nature of the Self will manifest, a process that occurs as the attachment to the form itself (the Saguna) eventually vanishes, revealing the formless reality.
