What are the core teachings and stories presented in Chapter 27 of the Sai Satcharitra?

Chapter 27 of the Sai Satcharitra primarily focuses on the profound importance of devotion to the Sadguru. It begins by equating holding the Guru's feet with saluting the Supreme Brahman itself, describing the Guru as a manifest embodiment of self-bliss. The text details the physical and emotional signs of a true devotee, such as perspiration and tears of love, which signify the awakening of Guru's grace. As described in Chapter 27, overcoming the illusion of Maya and worldly attachments requires singular devotion to Sai. The chapter concludes with a brief historical note about Chandbhai Patil bringing Sai Baba from the Nizam's state to Newasa, where he resided for six months.
