Why does Chapter 11 of the Sai Satcharitra advocate for devotion to a Guru in a manifest (Saguna) form?

Chapter 11 strongly advocates for devotion to a Saguna, or manifest, Guru for several practical and philosophical reasons. The chapter explains that as long as the worshipper themselves possesses a physical form or body, the Guru must also be in a physical form for devotion to be effective; this is presented as the determination of the scriptures. It argues that without meditating on a manifest form, genuine loving devotion can never fully manifest in a person. A physical form is deemed necessary because it provides a tangible focus for worship—a being in whose company one can exchange words of love, at whose feet one can place their head, and who can be worshipped with offerings.
