What is the significance of meditating on Sai's physical (Saguna) form as mentioned in Chapter 52?

Chapter 52 highlights the importance of the Saguna, or physical form, as a means to spiritual realization. The text posits that by meditating immensely on Sai's physical form, the subtle nature of the Self will eventually manifest as the perception of the Saguna form vanishes. It argues that one cannot know the light of the Self without first entering the Saguna form. This is because the Parabrahma, which is without attributes, is described as being entirely difficult to understand directly, making the tangible form a crucial gateway to comprehending the formless divine.
