What is the 'Satya-Sai vow' mentioned in Chapter 13, and how is it compared to the Satyanarayan vow?

The 'Satya-Sai vow,' as explained in Chapter 13, is a devotional practice initiated by the Patil to honor Sai Baba after his healing. It is directly modeled on the traditional 'Satyanarayan' vow, which people perform to overcome a crisis. The Patil adapted this ritual for his devotion to Sai. The primary difference is the sacred text used; instead of the Satyanarayan story, the Patil's vow involved reading the three chapters about Sainath from Das Ganu's 'Bhaktalilamrut.' Chapter 13 draws a direct and significant parallel, stating, 'There it is Narayan, here it is Sai; there is no difference in either,' underscoring the Patil's belief that Sai was a manifestation of the divine, worthy of the same form of worship.
