According to Chapter 22, what is the paradoxical nature of the Sadguru regarding form, illusion, and ultimate reality?

Chapter 22 of the Shri Sai Satcharitra delves into the complex, paradoxical nature of the Sadguru. It describes the Guru as being present before illusion, in a state of "total darkness" where he is formless. However, the text also identifies the Guru as the cause of the "dim light"—the very condition that allows for illusion to arise, like a rope appearing as a snake. As the chapter states, "the form of the formless, which is the occasion of dim light; by that, the venomous snake began to appear; You are also the cause of that illusion." This profound teaching suggests the Sadguru's nature transcends dualities, being both the source of illusion and the ultimate reality that dispels it. This truth is so deep that, as the text notes, even the Vedas became silent in attempting to describe it.
