Why does Chapter 11 of the Satcharitra emphasize worshipping a Guru with a physical form (Saguna)?

Chapter 11 of the Shri Sai Satcharitra strongly advocates for devotion to a Saguna, or manifest, Guru. The text explains that as long as the worshipper has a physical body, the Guru must also be in a physical form for devotion to properly manifest. It posits that without meditating on this tangible form, true loving devotion cannot arise, comparing it to a flower bud that cannot open and release its fragrance without blooming. According to the chapter, this devotion to the manifest form is a necessary step, as the scriptures determine that for the formless, the formless is suitable, but for those with form, a Guru with form is the appropriate path. This approach allows the devotee to experience the wonders of Guru-worship directly.
