How does Chapter 27 contrast the illusory nature of worldly life with the path of spiritual devotion?

Chapter 27 provides a deep philosophical contrast between worldly attachments and spiritual reality. It describes the business of 'I' and 'mine'—related to one's body, home, son, and wife—as a vain and momentary illusion (Maya), comparing it to a fleeting shadow at noon. To overcome this entanglement, the chapter advises singular devotion and surrender to Sai. It posits that while even the Vedas and Shastras have struggled to understand Maya, the one who sees God in all beings, through the grace of the Guru, will surely be saved from its clutches.
