How does Chapter 27 contrast the transient nature of Maya with the eternal value of devotion to the Sadguru?

Chapter 27 draws a sharp contrast between worldly attachments and spiritual devotion. It dismisses the "business of 'I' and 'mine'," including one's body, home, son, and wife, as "momentary Maya," comparing it to a fleeting shadow at noon. The chapter suggests that even the Vedas and Shastras have given up trying to find an end to this entanglement. In contrast, as described in Chapter 27, it presents devotion to the Sadguru as the definitive solution. One must surrender to Sai with singular devotion to ensure Maya does not obstruct them, thereby attaining self-knowledge and liberation from the illusory world.
