What's the spiritual lesson from the story where Dev couldn't recognize Baba as the Sanyasi at his feast?

The story of Dev's Udyapan feast in Chapter 40 illustrates that divine presence can manifest in unexpected ways and that our own preconceptions can blind us to it. Dev was looking for Baba but failed to recognize Him in the humble guise of a Sanyasi, partly due to a prior encounter that fixed a different identity in his mind. He later lamented his "pride of knowledge" and admitted that a "delusion fell" upon him. The lesson is about the importance of being attentive, humble, and open-minded, as Baba always keeps His word, though His methods may be mysterious and test a devotee's perception and faith.
