According to the start of Chapter 21, what makes a spiritual narration truly effective?

The beginning of Chapter 21 sets a standard for what constitutes a powerful spiritual narration. It suggests that a speaker's words are only successful if they evoke a profound physical and emotional response from the listener. The text considers narrations futile if the listeners are not delighted, if their throats do not "choke up with emotion," and if "tears of love and joy do not flow from the eyes." It also mentions that the listener should sway upon hearing the words and feel the hair on their body stand on end. This implies that the goal of such stories, particularly Baba's, is to create a deeply moving and transformative experience rather than just conveying information.
