Based on Chapter 41, what is the power of a Guru's grace and how can a devotee properly receive it?

Chapter 41 explains that the Guru's grace has transformative power that cannot be attained by great effort alone but is set in motion by the Guru's will. To receive this, a devotee must focus their 'inner being on the Guru’s feet with love.' The text states that by singing and listening to the Guru's greatness, the mind becomes pure, and through meditation and repeating His name, the Guru's presence manifests. It is through this loving devotion that a devotee can experience how the Guru tirelessly looks after their well-being. Even those who came with pride to inspect Sai Baba, as mentioned in this chapter, ended up abandoning their ego, happy with the joy of His Darshan, demonstrating the profound effect of His grace.
