According to Chapter 13, how did the Patil's new devotional practice compare to the traditional Satyanarayan puja?

Chapter 13 explains that the Patil modeled his 'Satya-Sai vow' directly on the traditional Satyanarayan puja. Just as people would vow to perform the Satyanarayan ritual to be freed from a crisis, the Patil began his vow to honor Sai for his healing. The comparison is quite direct: the Patil would observe his vow on Thursdays, just as one might for a traditional puja. While people read the Satyanarayan story, the Patil would instead read the three chapters on Sainath from Das Ganu's book. The text also mentions 'the same abundance of offering (Naivedya) and the same auspicious celebration,' culminating in the idea that there is no fundamental difference between the two, as Narayan and Sai are one and the same.
