How did Dev react after he learned that the Sanyasi at his feast was actually Sai Baba in disguise?

Upon receiving a detailed letter from Jog explaining that the Sanyasi was indeed Sai Baba, Dev was overcome with emotion. Chapter 40 describes that his 'eyes overflowed with a surge of love.' He felt immense regret and shame for his lack of perception, exclaiming, 'Shame, shame! I blamed Sai in vain!' Dev felt very dejected, realizing he had misjudged the situation and wrongly accused Baba. He recognized the greatness of Baba and felt shame for his own 'pride of knowledge,' wondering how he could have failed to guess Baba's presence. This realization transformed his disappointment into a profound sense of remorse and renewed reverence for Sai Baba's power.
