Why does Chapter 11 of the Sai Satcharitra emphasize devotion to a Guru with a physical form?

Chapter 11 of the Sai Satcharitra emphasizes devotion to a manifest (Saguna) Guru because, as the text explains, a devotee who has a physical form requires a Guru who is also in a physical form. The scriptures determine that "for the formless, the formless is suitable," but for an embodied worshipper, this is the necessary path. According to the chapter, devotion cannot truly manifest without meditating on a Saguna form. This meditation is crucial because, as long as loving devotion doesn't occur, the "bud of the mind does not open," preventing spiritual fragrance and nectar from being experienced. Thus, for the devotee's mind to bloom, devotion to the manifest form of the Guru is essential.
