What specific devotional practices did the Patil adopt after being cured by Sai Baba, as described in Chapter 13?

Following his miraculous healing, the Patil's life was transformed by devotion, as detailed in Chapter 13. His first act was to seek the darshan of Baba, where he was overwhelmed with joy and love, placing his forehead on Sai's feet in total surrender. He then stayed in Shirdi for a month, singing praises. Most notably, he initiated a new tradition called the 'Satya-Sai vow.' As Chapter 13 describes, every Thursday he would perform this vow, which involved reading the three chapters about Sainath from the 'Bhaktalilamrut' written by Das Ganu. This practice, born of immense gratitude, brought him boundless happiness and peace.
