Describe the incident where Das Ganu wanted to go on a pilgrimage and what Sai Baba did to show him it was unnecessary.

Chapter 4 details an event where Das Ganu, feeling the desire to bathe in the holy Prayag on a special day, went to ask for Sai Baba's permission. Baba advised him against the long journey, stating, 'This itself is our Prayag; keep firm faith in your mind.' To demonstrate this profound truth, a miracle occurred. As Das Ganu bowed to Baba's feet, water representing the sacred Ganga and Yamuna rivers began to drip from His big toes. Witnessing this incredible event, Das Ganu was overcome with emotion and tears, realizing the immense power and grace of his Guru. The experience taught him that true pilgrimage and holiness reside at the feet of the Master, making external journeys superfluous if one has true faith.
