Why does Chapter 11 of the Sai Satcharitra stress the importance of worshipping a Guru who has a physical form?

Chapter 11 of the Sai Satcharitra places great emphasis on devotion to a Saguna, or manifest, Guru with a physical form. The text argues that because a devotee has a physical form, a Guru in a physical form is also necessary to establish a tangible relationship. It is through meditating on this manifest form that true devotion arises, which is needed for the 'bud of the mind' to open. The chapter highlights the practical aspects of this, noting that a physical form is required for acts of worship like placing one's head at the Guru's feet, exchanging words of love, or making offerings. As Chapter 11 clearly states, understanding the Saguna is much easier than grasping the abstract Nirguna, and it is through firm love for the manifest form that one eventually realizes the formless.
