Why does Chapter 11 argue that devotion to a Guru with a physical form is necessary for a spiritual seeker?

Chapter 11 strongly advocates for the necessity of a manifest (Saguna) Guru. The text makes the case that as long as the worshipper possesses a physical body or form, the Guru must also be in a physical form to facilitate true devotion. It states that without meditating on this manifest form, devotion can never truly arise. The chapter uses a beautiful metaphor, explaining that until loving devotion occurs, the "bud of the mind does not open." If the mind doesn't bloom, it lacks fragrance and nectar, meaning it cannot attract the bee of divine wisdom. Therefore, according to the teachings in this chapter, the manifest Guru is the essential gateway for a seeker to experience the wonders of Guru-worship and achieve spiritual blossoming.
