Analyze the interplay between divine grace, free will, and karmic destiny as presented in Chapter 47.

Chapter 47 presents a sophisticated interplay between these concepts. It establishes divine grace as a powerful, liberating force, noting that Sai's "merciful glance" can instantly sever the "bonds of Karma." Simultaneously, it upholds the strict law of Karma, where birth is determined by past actions. The element of free will, or human agency, is highlighted through the exhortation to "Perform your worldly duties daily" and to use the "priceless opportunity of human birth" to attain self-knowledge. This suggests that while karmic destiny sets the stage, an individual's conscious actions and devotion to a guru like Sai provide the path to transcending that destiny. Thus, as per this chapter, grace does not erase Karma but provides the means to overcome it through wise action.
