How does Chapter 12 describe the form and essence of a Sadguru like Sainath, and who is able to perceive it?

Chapter 12 of the Shri Sai Satcharitra presents a profound description of the Sadguru's essence. It states that just as the sky expands to fill all places, so is the Guru's form depicted, suggesting a boundless and all-pervading presence. He is described as the embodiment of Truth, Consciousness, and Bliss, the source of all joy. The text emphasizes that this expansive, true form is not perceived by everyone; it is explicitly stated that only the virtuous and fortunate are able to experience this reality. Through the knowledge of non-duality, the Guru removes the obsession with duality from a devotee's mind.
