How does the provided text explain the relationship between a Guru's power and the law of karma?

The text explores the complex relationship between a Guru's power and karma through the narrator's internal conflict. After hearing about a friend whose Guru could not save his son from death, the narrator questions the efficacy of spiritual masters. Chapter 2 highlights his thoughts: "Is this the benefit of a Guru's company? What can Gurus do against Karma?" The passage suggests that karma is a powerful, perhaps even supreme, force, stating that "Every living being is governed by the system of Karma; destiny is everywhere irresistible." This implies that even a Guru's grace may not override the predetermined course of events, presenting a nuanced view where a Guru's role might exist alongside the unchangeable reality of karma.
