Can you summarize the main themes of Chapter 21 of Sai Satcharitra?

Chapter 21 of the Sai Satcharitra primarily revolves around two key themes. The first is that the ability to meet and benefit from the company of Saints is a privilege reserved for the fortunate, requiring God's grace. The author illustrates this by narrating his own past failure to visit the saint Pir Maulana due to his own "ill-luck." The second major theme is the intrinsic unity among all Saints. The chapter teaches that despite appearing in different times, places, and forms, all Saints are "essentially inseparable" and "inwardly, they are all one." This points to a secret, divine network and a shared consciousness that transcends physical separation, as explained within the sweet stories of Chapter 21.
