Why did Sai Baba tell Das Ganu not to go to Prayag for a holy bath, and what happened next?

Sai Baba often taught that true holiness was a matter of faith, not geography. As described in Chapter 4, when Das Ganu desired to go to Prayag for a holy bath on a special day, Baba advised against it, saying, "No need to go so far. This itself is our Prayag; keep firm faith in your mind." To prove his words, a miracle occurred. When Das Ganu bowed to Baba's feet, water from the sacred rivers Ganga and Yamuna began to drip from Baba's big toes. Witnessing this incredible event, Das Ganu was overcome with emotion and was inspired to compose a song about Baba's unfathomable power, realizing that the feet of a Saint are the holiest of pilgrimage sites.
