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

Chapter 52 explains the progression from worshiping the form (Saguna) to realizing the formless (Nirguna). It states that by meditating immensely on Sai's physical form, the devotee can begin to perceive the subtle nature of the true Self as the attachment to the physical form vanishes. The chapter posits that one cannot know the light of the Self without first entering the Saguna form, because the Parabrahma, which is without attributes, is entirely difficult to understand directly. Therefore, as detailed in Chapter 52, meditating on Sai's manifested form is a crucial and necessary step for a devotee to be led toward the supreme goal of understanding the formless absolute.
