According to Chapter 13, how did the Patil express his gratitude after being cured, and what new tradition did this lead to?

After his miraculous healing, the Patil was overwhelmed with gratitude and joy. Chapter 13 describes him going for Baba's darshan, where his 'ocean of joy' became filled, and he placed his forehead on Baba's feet in an act of total surrender. He believed this was the only way to repay the 'inconceivable' favor. This profound devotion inspired him to establish a new tradition: the 'Satya-Sai vow.' This practice, modeled after the common Satyanarayan vow, became his way of expressing continuous gratitude. On Thursdays, he would ritually read the three chapters about Sai written by Das Ganu in the 'Bhaktalilamrut,' transforming his personal gratitude into a regular devotional practice that spread in his village.
