What philosophical insights does Chapter 47 offer regarding the law of Karma?

Chapter 47 provides several insights into the concept of Karma. It begins by stating that a merciful glance from Shri Sai can immediately liberate a devotee from the "bonds of Karma." Later, the text describes the law of Karma as being "very deep; no one can comprehend it," so much so that even the "highly learned are deceived." However, it offers a path for devotees by noting that "the ignorant but faithful are saved." This implies that while Karma is incomprehensibly complex, unwavering faith in a protector like Sai provides a means of salvation and navigating its effects, a theme highlighted in the latter part of Chapter 47.
