Can you describe the interactions between Gangagir Baba, Anandnath Maharaj, and Sai Baba based on the provided text?

The source material describes profound interactions between Sai Baba and other contemporary saints who immediately recognized his spiritual eminence. Chapter 0 recounts that when Gangagir Baba first saw Maharaj, he proclaimed him a "gem" of great worth. Following this, the two had "great affectionate conversations." In a separate instance, Anandnath Maharaj of Akkalkot spontaneously decided to travel to Shirdi with some devotees. Upon his arrival, he echoed Gangagir Baba's sentiment, stating, "This is a diamond. You don't know its true value." These accounts demonstrate how other advanced spiritual figures perceived Maharaj's divine nature.
