Why does Chapter 11 stress the importance of worshipping a Guru with a physical form?

According to Chapter 11, devotion to a Guru with a physical, manifest form (Saguna) is essential for a devotee who also possesses a physical body. The text argues that devotion cannot truly manifest without meditating on this Saguna form. It uses an analogy, stating that until loving devotion occurs, 'the bud of the mind does not open.' Just as a flower must bloom to release its fragrance and attract a bee, the mind must open through manifest devotion. The scriptures, as cited in this chapter, determine that for a worshipper with a form, the Guru must also be in a physical form to facilitate this spiritual blossoming.
