Chapter 52 mentions meditating on Sai's physical form. Can you explain the relationship between worshipping the form (Saguna) and realizing the formless (Nirguna) based on this chapter?

Chapter 52 explains that meditating on Sai's physical, or Saguna, form is a vital step toward realizing the formless Absolute. The text states that by meditating immensely on Sai's physical form, the subtle nature of the Self will eventually manifest as the Saguna form itself vanishes from the mind's eye. It clarifies that without first engaging with the Saguna, the light of the Self cannot be known. This is because the Parabrahma, which is without attributes (Nirguna), is described as entirely difficult to understand directly. Therefore, Chapter 52 presents the worship of the form as the necessary and accessible pathway to comprehending the formless.
