Why did Sai Baba tell Das Ganu that he didn't need to travel to Prayag for a holy bath?

When Das Ganu expressed a desire to travel to Prayag for a holy bath on a special day, Sai Baba advised against it, teaching a profound lesson about faith. As recounted in Chapter 4, Baba told him, "No need to go so far. This itself is our Prayag; keep firm faith in your mind." To substantiate this statement, a miracle occurred: as Das Ganu bowed to Baba's feet, water from the sacred Ganga and Yamuna rivers began to drip from Baba's big toes. This powerful leela demonstrated to Das Ganu that the sanctity of holy places was accessible in the very presence of the Guru and that Shirdi itself was a potent pilgrimage site, making long journeys unnecessary for a true devotee.
