What does Chapter 18 say about the Guru's method of teaching and the relationship between the speaker and listener?

Chapter 18 explains that the Guru shows the true path through instruction tailored to each person's individual worthiness, without creating intellectual conflict. It also highlights the dynamic between a speaker and listener, stating that when a listener is attentive, the speaker feels enthusiasm, and a spring of love overflows, bringing joy to both. The chapter suggests that for one's own benefit, these stories and teachings should be heard with a calm mind. The Guru's method is compared to that of monsoon clouds, showering the 'water of self-bliss with love' universally.
