Based on the provided text, how does an individual's personal experience with tragedy shape their understanding of karma versus the role of a spiritual guide?

The narrative in Chapter 2 poignantly illustrates how personal tragedy can lead to profound spiritual questioning. When the narrator learns that his friend's son died despite the presence of a Guru, his logic-driven mind immediately grapples with the concept. He concludes that "Every living being is governed by the system of Karma; destiny is everywhere irresistible." This leads him to a state of restlessness and doubt, making him question the very purpose of seeking a Guru. He thinks, "What is the use of going to a Guru if nothing works against what is to happen?" This shows how the raw power of a seemingly unchangeable destiny can make one initially perceive the role of a Guru as futile against the force of karma.
