According to Chapter 11, why is having a physical Guru, or 'Saguna' form, so important for a devotee's spiritual progress?

Chapter 11 stresses the necessity of a physical Guru for a devotee's spiritual journey. The text makes the point that as long as the worshipper has a physical body, the Guru must also be in a physical form to facilitate a tangible connection. It is through this manifest form that a devotee can perform acts of worship, place their head at the Guru's feet, and exchange words of love, all of which are crucial for nurturing devotion. As Chapter 11 explains, without meditating on the manifest form, loving devotion does not arise, and without that love, the 'bud of the mind does not open.' This devotion to the Saguna is presented as the most accessible path toward the eventual realization of the formless Supreme Brahman.
