The beginning of the story about Amir mentions someone praying for calamities. What is the significance of this prayer?

The passage in Chapter 22 begins by recounting the prayer of a woman who, despite suffering infinite calamities, asked God for a constant series of sorrows. Her reasoning was that sorrow would prevent her from ever forgetting God's name, making it an 'eternal ornament on my neck.' This philosophical point serves as a prelude to Amir's story, framing it within the theme of absolute faith and surrender. The text suggests that all devotees should similarly pray to Sai to remain at His feet and never forget His name, highlighting that even seemingly negative circumstances can be a path to deeper devotion.
