Why does Chapter 11 emphasize the importance of having a Guru with a physical form?

Chapter 11 argues that having a Guru in a physical, manifest (Saguna) form is essential for a devotee who also has a physical form. The text states, "As long as the worshipper has a form (body), the Guru must also be in a physical form." It further explains that devotion cannot truly manifest without meditating on this Saguna form. This meditation is what allows the 'bud of the mind' to open and bloom, which is a necessary step for spiritual growth. For the formless, the formless is suitable, but for embodied beings, a manifest Guru is the determined path according to the scriptures.
