How does Chapter 11 explain the concept of worshipping a Guru with a physical form?

Chapter 11 provides a detailed philosophical explanation for why devotion to a Guru in a physical, or Saguna, form is essential for a devotee who also has a physical body. The text states that as long as the worshipper has a form, the Guru must also be in a physical form, citing this as a determination of the scriptures. According to Chapter 11, devotion cannot truly manifest without meditating on this Saguna form. It uses an analogy, explaining that unless the 'bud of the mind' opens through loving devotion, it has no fragrance or nectar to offer. The chapter clarifies that the manifest ('Sakara') and unmanifest ('Nirakara') are not different, but two states of the same reality.
