Why does Chapter 11 emphasize the importance of worshipping a Guru in a physical, manifest form?

Chapter 11 of the Sai Satcharitra strongly advocates for devotion to a Saguna, or manifest, Guru. It argues that as long as a worshipper has a physical body, the Guru must also be in a physical form to guide them effectively. The text states that without meditating on the manifest form, true devotion cannot arise. This physical form allows for tangible acts of worship, such as placing one's head at the Guru's feet and exchanging words of love. The chapter posits that understanding the Saguna is much easier than grasping the Nirguna (unmanifest) and that establishing firm love for the manifest form is the necessary first step toward realizing the formless.
