What was Dev's emotional state after he found out that the Sanyasi at his feast was really Sai Baba?

Upon receiving a letter from Jog that explained everything, Dev was overcome with emotion. As Chapter 40 recounts, Dev's "eyes overflowed with a surge of love." He felt immense regret and shame for having doubted and blamed Sai Baba, exclaiming, "Shame, shame! I blamed Sai in vain!" He felt very dejected in his mind, acknowledging Baba's greatness while lamenting the "pride of my knowledge" that had blinded him to the truth of who was present at his meal.
