How did Dev react when he finally learned the truth about Sai Baba's attendance at his ceremony?

Upon receiving a detailed letter from Jog explaining the truth, Dev's reaction was one of profound remorse and overwhelming love. Chapter 40 states that upon reading the letter, Dev's "eyes overflowed with a surge of love." He felt deeply dejected for having misjudged the situation, exclaiming, "Shame, shame! I blamed Sai in vain!" This revelation caused him to criticize his own pride and ignorance while marveling at Baba's greatness. His disappointment was instantly transformed into reverence and regret for his doubt, showing a complete shift in his emotional and spiritual state.
