How does Chapter 11 explain the difference between a manifest (Saguna) and unmanifest (Nirguna) Guru?

Chapter 11 of the Sai Satcharitra explains that the manifest (Saguna, with form) and unmanifest (Nirguna, formless) are not different from each other, but are two states of the same reality. The text uses an analogy, stating that just as ghee is called ghee whether it is frozen (with form) or melted (formless), the divine is one and the same in both its manifest and unmanifest states. The chapter emphasizes that for a devotee who has a physical body, meditating on the manifest, physical form of the Guru is essential for devotion to arise and the mind to open.
