Chapter 52 discusses both the physical form (Saguna) and the formless (Nirguna) nature of the divine. How does devotion to Sai's physical form lead to understanding the formless Absolute?

According to Chapter 52, devotion to Sai's physical form, or Saguna, is the necessary first step to comprehending the formless Absolute, or Nirguna. The text explains that by meditating immensely on Sai's physical form, the subtle nature of the Self will manifest as the Saguna form eventually vanishes. It explicitly states that without first entering the Saguna form, the light of the Self cannot be known because the Parabrahma, which is without attributes, is entirely difficult to understand on its own. Sai Baba, by showing His own feet and fostering love for His form, mysteriously led His faithful devotees towards the supreme goal of liberation while they were still in their bodies.
