Based on Chapter 52, what is the significance of meditating on Sai Baba's physical form (Saguna) in the journey toward spiritual realization?

Chapter 52 describes the importance of meditating on Sai Baba's physical form, or Saguna. It explains that by meditating immensely on Sai's form, the subtle nature of the Self will manifest as the perception of that physical form vanishes. The chapter underscores this method by stating that without first entering the Saguna form, the light of the Self cannot be known. This is because the formless Absolute, or Parabrahma which is without attributes, is considered entirely difficult to understand directly. Therefore, meditating on the Guru's form is presented as the essential and accessible pathway to realizing the formless reality.
