Can you explain the relationship between surrendering to the Guru and overcoming the illusions of Maya, as detailed in the source text?

The source text from Chapter 27 emphasizes that attachments of 'I' and 'mine'—concerning body, home, son, and wife—are fleeting illusions, or Maya, like a shadow at noon. To prevent these entanglements from obstructing one's spiritual path, the text advises surrendering to Sai with singular devotion. It is stated that even the Vedas and Shastras have given up trying to find the end of Maya. The true path to salvation and overcoming this illusion is through the Guru's grace, which is achieved by seeing God in all beings and surrendering completely to the Sadguru.
