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

Upon receiving a detailed letter from Jog that explained how Sai Baba had attended his Udyapan ceremony in the guise of a Sanyasi, Dev had a powerful emotional reaction. According to chapter 40, Dev's eyes overflowed with love as he read the account. He was filled with remorse and felt dejected, exclaiming, "Shame, shame! I blamed Sai in vain!" He felt shame for the pride of his own knowledge that had blinded him and prevented him from recognizing his Guru. This realization transformed his disappointment into a profound appreciation for Baba's greatness and the mysterious ways in which He operated.
