What was the author's motivation for writing the Sai Satcharita, based on his reflections in Chapter 49?

Based on the reflections in Chapter 49, the author's motivation was twofold, stemming from both a desire to share bliss and a sense of divine compulsion. He likens the experience of Sai's stories to a feast of "sweet delicacies" and explains that one doesn't enjoy such a feast alone; its sweetness turns bland without friends. This desire to share the "bliss of the self-essence" with other devotees was a key motivator. Concurrently, he admits the book was started for his "own self-interest." Most importantly, he attributes the entire project to Sai's will, stating that Sai prompted him to start the Satcharita and provided the stories and remembrance needed to complete it, making the author a willing channel for Sai's grace.
