How does the text explain the interplay between individual doubt, past karma, and destiny regarding the narrator's journey to Shirdi?

Chapter 2 presents a complex interplay of forces. The narrator, described as a staunch debater, initially resists going to Shirdi. His journey is first arranged due to Kakasaheb's insistence. However, his personal logic causes him to cancel after hearing news that makes him doubt the power of Gurus against karma. He rationalizes that one should just accept what happens. Yet, the text ultimately attributes his eventual journey to an irresistible destiny, stating, "Nothing works against destiny; it dragged me to Shirdi." This suggests that while he experienced doubt and made choices, a deeper karmic path, perhaps linked to his "past life connection," ultimately guided his actions beyond his conscious objections.
