What motivated the author to share Sai's stories with others instead of keeping the experience to himself?

The author's motivation to share Sai's stories stemmed from a desire to spread the bliss he experienced. As described in Chapter 49, when the author's tongue tasted the "sweet delicacies" of Sai's stories, his mind immediately thought of the "circle of listeners." He felt that they too should be brought to this spiritual feast, believing that the bliss of the self-essence would double when shared. He compares the experience to enjoying a wonderful sweet, noting that its sweetness turns bland if not shared with friends and virtuous people. This altruistic thought took root in his soul, leading to the creation of the Satcharita.
