What does the author Hemad state in Chapter 43 about the significance of recounting the lives of saints like Sai?

In Chapter 43, the author Hemad reflects on the spiritual benefits of engaging with the stories of saints. He posits that to wash away the "filth of accumulated sins" and purify one's inner self, there is no easier means than the remembrance, bhajan (devotional singing), or kirtan (devotional chanting) of God's devotees. He also notes that while the topic of death can be wearying, the passing of saints and sages is a special case that purifies both the listeners and the speakers. Hemad expresses his own devotion, acknowledging that Sai himself grants the love and devotion needed to write this life story.
