How did Sai Baba prove to Das Ganu that Shirdi itself was a holy pilgrimage site?

Das Ganu once felt a strong desire to bathe in the holy Prayag (the confluence of the Ganga and Yamuna rivers) on a special day and sought Baba's permission. As Chapter 4 recounts, Baba advised him against traveling, stating, "No need to go so far. This itself is our Prayag; keep firm faith in your mind." To demonstrate this, a miracle occurred when Das Ganu bowed at Baba's feet. Water, representing the sacred Ganga and Yamuna, began to drip from Baba's two big toes. Witnessing this incredible event, Das Ganu was overcome with emotion and his faith was solidified. This leela showed that for a true devotee, the Guru's feet are the holiest of all tirthas, and one need not undertake long journeys for spiritual purification if they have unwavering faith.
