According to the source, what is the dual purpose of listening to the life stories of saints like Sai Baba?

Chapter 14 reveals that the life stories of saints serve a dual purpose, addressing both worldly and spiritual aspects of life. On one hand, these stories are described as inherently sweet and a source of self-bliss, allowing devotees to experience joy through remembrance. On the other hand, they are not just simple biographies. As the chapter explains, while telling stories that seem to involve worldly matters, Sai Baba subtly leads the devotee towards the path of renunciation. The ultimate purpose is to help people live happily in the world while remaining spiritually alert, thereby making their human life meaningful.
