Why is devotion to a Guru in a physical form considered important in the teachings of Chapter 11?

Chapter 11 emphasizes the importance of a physical Guru because, as the text states, 'as long as the worshipper has a form (body), the Guru must also be in a physical form.' A manifest Guru provides a tangible focus for devotion. It allows a devotee to perform acts of worship like placing their head at the Guru's feet, exchanging words of love, and offering sandalwood and grains. The chapter explains that without meditating on this manifest (Saguna) form, true devotion cannot manifest, and the mind cannot blossom. This tangible connection is presented as a crucial step toward spiritual realization.
