How does Chapter 27 interlink the concepts of the Guru's grace, a devotee's spiritual progress, and the entanglement of Maya?

Chapter 27 intricately connects the Guru's grace, a devotee's progress, and the illusion of Maya. The text posits that the Guru's grace is the catalyst for spiritual advancement, which is accessed through unwavering faith and devotion. This devotion is demonstrated by emotionally and physically engaging with the Guru's stories. The chapter states that the Guru feels joy as the devotee turns to the spiritual path. This journey's primary obstacle is Maya—the attachment to the material world. Chapter 27 teaches that surrendering to the Sadguru with singular devotion is the only effective method to overcome Maya's entanglement, a feat that even scriptures find difficult.
