Based on Chapter 22, how is Sai Baba depicted as the formless, absolute reality?

Chapter 22 portrays Sai Baba not just as a physical Guru but as the supreme, formless reality that precedes all creation and duality. After discussing the illusion of the snake and rope, the chapter elevates the concept by stating, "Before, when there was total darkness, there was no snake and no rope. There was no place for a tendency to arise; That formless one is also You." This powerful verse from Chapter 22 identifies Baba with the primordial, attributeless state beyond perception. The chapter further reinforces this by mentioning that the Vedas fell silent and even the celestial serpent Shesha could not grasp His true nature, affirming that Baba is the ultimate, unknowable source of all existence, the "form of knowledge, the supreme purifier."
