Chapter 11 talks about Saguna and Nirguna. Can you explain why it says worshipping a Guru with a physical form is important?

Chapter 11 emphasizes the importance of devotion to a Saguna, or manifest, Guru. The text explains that as long as a devotee has a physical body, the Guru must also be in a physical form for worship to be effective. According to this chapter, meditating on the manifest form is what allows devotion to truly blossom within a person, which in turn opens the bud of the mind. The chapter beautifully clarifies that the manifest (Sakara) and unmanifest (Nirakara) are not different but are one and the same, using the analogy of ghee, which is still ghee whether it is frozen or melted. Thus, the physical Guru is the tangible form of the formless Supreme Brahman.
