How does Chapter 41 illustrate the concept of a Guru's grace and its effect on devotees?

In Chapter 41, the power of a Guru's grace is presented as a transformative force that accomplishes what great personal effort cannot. The text explains that by focusing one's inner being on the Guru's feet with love, a devotee can experience how the Guru tirelessly looks after their well-being. This state of grace isn't obtained by asking but is found through immersing oneself in the Guru's glory. The chapter highlights that even those who approach with ego and pride, intending to scrutinize, end up abandoning their ego and returning happy after receiving Sai's Darshan. This demonstrates how the Guru's grace can effortlessly bring about inner change and fulfillment.
