What specific action by Deo provoked Sai Baba's anger, and what did it teach him about approaching the Guru?

Sai Baba's intense anger towards Deo was provoked by a very specific action, as detailed in Chapter 41. Deo had approached another devotee, Balkram, and asked him, "How do you meditate on Parahbrahman?" This act of making inquiries with someone else when the Guru Himself was available was precisely what Baba disliked. Baba's subsequent outburst and metaphorical scolding about 'stealing rags' taught Deo a crucial lesson: he should not seek spiritual knowledge from secondary sources when the primary source of all wisdom was readily accessible. The incident underscored the principle that a devotee must have complete faith in their Guru and direct all their ultimate questions to him.
