Why does Chapter 11 emphasize the necessity of a physical Guru for a devotee?

Chapter 11 strongly advocates for the necessity of a physical, or manifest, Guru for a person on the spiritual path. It makes the point that as long as the worshipper possesses a physical body, the Guru must also be in a physical form for devotion to be practical and effective. The chapter highlights the tangible benefits of a manifest Guru, noting that this is the form where one can physically place their head at the feet, exchange words of love, and perform worship with offerings like sandalwood. According to Chapter 11, understanding the Saguna (manifest) is much easier than the Nirguna (unmanifest), and it is through firm devotion to the manifest form that the mind opens and realization of the formless can eventually occur.
