How did the seemingly cruel punishments the Patil experienced in his dream lead to a deeper form of devotion?

The Patil's story in Chapter 13 is a profound lesson on how faith can be forged through hardship. The punishments in his dream—being beaten with a cane and having his chest crushed by a grinding stone—were agonizing. However, this suffering was the direct cause of his miraculous cure. The text notes that the "punishment by the cane and the bursting of the heart—the result was clearly beneficial." This experience taught the Patil that Sai Baba's methods, while "inconceivable and unfathomable," were ultimately for his good. This realization transformed his fear and suffering into immense gratitude and strengthened faith, inspiring him to create and regularly perform the 'Satya-Sai vow' as a new, heartfelt form of worship, as detailed in Chapter 13.
