What is the spiritual risk for a disciple who questions the Prasad given by their Guru?

Chapter 38 puts forth a strong spiritual principle regarding a disciple's faith. It suggests that if a disciple receives Prasad from their Guru and starts to entertain doubts about whether it is edible or inedible, that disciple "suffers spiritual suicide and goes toward a downfall." This implies that absolute faith and surrender are paramount in the Guru-disciple relationship. The text uses the story of Dada Kelkar to illustrate that a Guru's seemingly strange commands are often tests of faith. The highest form of devotion is not material offerings but the complete and faithful execution of the Guru's orders, which signifies true surrender.
