What was Dev's emotional reaction when he finally learned that the Sanyasi at his feast was actually Sai Baba?

When Dev learned the truth, his disappointment and doubt were instantly replaced by overwhelming love and remorse. Chapter 40 vividly describes his reaction upon reading the letter from Jog that explained everything. The text says, "Dev read the letter; his eyes overflowed with a surge of love." He felt deep regret for his lack of faith, exclaiming, "Shame, shame! I blamed Sai in vain!" and felt "very dejected in his mind." Dev realized that his own "pride of my knowledge" had blinded him to Baba's divine presence, leading to a profound sense of humility and a renewed appreciation for Baba's greatness.
