Why was Dev still filled with doubt after serving the three uninvited guests, and what did he do about it?

Despite serving three uninvited guests in person, Dev remained doubtful because the experience was clouded by a 'veil of Maya,' and it did not unfold as he expected a visit from Baba would. Chapter 40 notes that his mind simply registered the Sanyasi as 'some guest who has come to get a meal,' strengthening his delusion. This uncertainty lingered even after the event. Feeling disappointed and confused, Dev wrote a letter to Jog seeking clarification. In the letter, he lamented, "How is it that Baba deceived me?" and questioned why he had no profound experience despite inviting Baba with love, showing that the mundane nature of the visit left him unconvinced and seeking external validation.
