At the beginning of Chapter 21, how does the author describe the ideal way to listen to Baba's stories and teachings?

At the start of Chapter 21, the author emphasizes that the power of Baba's stories lies in the listener's heartfelt reaction. He states that a speaker's words have 'gone in vain' if the listener 'does not sway upon hearing them' and if 'the hair on the body does not stand on end.' He considers narrations futile if they do not delight the listeners to the point where their 'throat does not choke up with emotion, and tears of love and joy do not flow from the eyes.' This description sets a high standard for engagement, suggesting that one should listen with an attentive mind and an open heart, allowing the captivating and extraordinary nature of Baba's life to evoke a deep, emotional, and even physical response.
