How did Sai Baba demonstrate to Das Ganu that Shirdi was as holy as Prayag?

Chapter 4 recounts a powerful leela where Das Ganu desired to travel to Prayag for a holy bath. When he sought Baba's permission, Baba advised against the long journey, stating, "This itself is our Prayag; keep firm faith in your mind." To substantiate this claim, a miracle occurred. As described in Chapter 4, when Das Ganu bowed at Baba's feet, water representing the sacred rivers Ganga and Yamuna began to drip from both of Baba's big toes. Witnessing this divine manifestation, Das Ganu was overcome with emotion and his desire to travel was quenched, proving to him that the sanctity of a holy place was present right there at his Guru's feet.
