Describe the portrayal of Shri Sai's divine nature and merciful power in Chapter 47.

Chapter 47 portrays Shri Sai as a divine being of immense power and compassion. He is called the "abode of supreme bliss," whose holy face can destroy the sorrows of infinite births upon being seen for just a moment. His merciful glance is said to immediately liberate devotees from the bonds of Karma. The chapter uses a powerful metaphor, stating that in the light of the sun of His grace, the "firefly of worldly existence" loses its luster. Furthermore, Chapter 47 presents Sai as a perpetual protector and the ultimate source of the Satcharitra's stories, explaining that Sai himself enters the author's heart to narrate the accounts.
