According to Chapter 22, what is the philosophical nature of the Sadguru in relation to form, formlessness, and human perception?

Chapter 22 presents a complex philosophical understanding of the Sadguru. It posits that the Sadguru is the ultimate, formless reality that existed in "total darkness" before any perception or duality. He is also the cause of the "dim light," the state of illusion where a rope can appear as a snake. This means He is the creator of both the illusion (the snake-like tendency) and the one who reveals its true nature (the rope). As the text in Chapter 22 explains, this nature is beyond concepts of being and non-being, a reality so profound that the Vedas fell silent and even celestial beings cannot fully comprehend it, highlighting the limitations of human perception in grasping the Sadguru's true, all-encompassing form.
