What is the significance of meditating on Sai's physical form (Saguna) in understanding the formless Self, according to Chapter 52?

Chapter 52 emphasizes the critical role of the Saguna, or the physical form, in spiritual realization. The text teaches that by meditating immensely on Sai's physical form, the subtle nature of the Self will eventually manifest as the Saguna form itself vanishes. It explicitly states that without first entering the Saguna form, the light of the Self cannot be known. This is because the Parabrahma, which is without attributes and formless, is described in Chapter 52 as being entirely difficult to understand directly. Therefore, devotion to the form is presented as the pathway to grasping the formless.
