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

Chapter 52 provides a philosophical explanation for this process. It states that by meditating immensely on Sai's physical form, the 'Saguna', the subtle nature of the Self will eventually manifest as the form itself vanishes. The text emphasizes that without first entering the Saguna form, the light of the Self, which is the formless Parabrahma, is entirely difficult to understand. This suggests that devotion to the manifest form is a crucial step toward realizing the unmanifest reality.
