According to the beginning of Chapter 21, what makes listening to Baba's stories a worthwhile experience?

The introduction to Chapter 21 emphasizes that the value of listening to Sai Baba's stories lies in the listener's emotional and spiritual response. The narration is considered futile or 'in vain' if it does not evoke a deep reaction. According to the text, a successful narration is one where 'the listener does not sway upon hearing them, if the hair on the body does not stand on end.' The experience is meant to be transformative, where listeners are 'delighted,' the 'throat does not choke up with emotion,' and 'tears of love and joy do not flow from the eyes.' This indicates that the stories are meant for heart-felt connection, not just intellectual understanding.
