Why does Chapter 11 of the Sai Satcharitra emphasize worshiping a Guru with a physical form? Isn't the ultimate reality formless?

Chapter 11 addresses this philosophical point directly. It explains that as long as the worshipper has a physical form or body, the Guru must also be in a physical, manifest (Saguna) form for devotion to truly arise. The text argues that without meditating on this manifest form, loving devotion cannot occur, and the mind will not spiritually blossom. However, it also clarifies that the manifest ('Sakara') and the unmanifest ('Nirakara') are not different; they are one and the same. As Chapter 11 illustrates with an analogy, just as ghee is still ghee whether it is frozen (with form) or melted (formless), the divine reality is one, pervading the universe in both its Saguna and Nirguna aspects.
