Can you summarize the introductory prayers and the main message about the Guru's grace in Chapter 27?

Chapter 27 begins with traditional salutations to various deities, culminating in a powerful praise of the Sadguru. The core message is that devotion to the Sadguru encompasses all other forms of worship. The text explains that holding onto the Guru's feet is the ultimate salutation and provides the merit of all pilgrimages. As Chapter 27 elaborates, the Guru's grace is an internal awakening, not something that can be perceived by the senses. This grace leads to the subsiding of passions like lust and the emergence of supreme love, but it requires ultimate faith from the devotee. The Guru, in turn, finds joy in the devotee's spiritual progress.
