What does the text say about the spiritual consequences of a disciple doubting the prasad given by their Guru?

Chapter 38 explains that the relationship between a Guru and a disciple regarding Prasad is a matter of profound spiritual importance. It states that if a disciple entertains a doubt about whether the Prasad given by the Guru is edible or inedible, the disciple suffers a form of "spiritual suicide" and heads towards a downfall. This principle was so important that Baba would use jokes and humor to help his devotees experience and understand it. The story of Dada Kelkar being asked to fetch meat is used as an example to illustrate this very point: true devotion lies in obeying the Guru's command without question, as that is the highest form of offering.
