Besides specific stories, what does the text say about the general power and purpose of Sai Baba's Udi?

Chapter 33 describes Sai Baba's Udi as "supremely auspicious" and produced in countless quantities. The text explains that the Udi has a dual purpose: it fulfills worldly interests while also serving as a guide for spiritual welfare. Baba is depicted as the "helmsman of the path of spiritual welfare," using the Udi as a tool to help his devotees navigate both their material and spiritual lives. The author notes that there are countless stories illustrating the benefits of the Udi but only a few are told in condensed form to avoid making the book too lengthy.
