What was the lasting legacy of Chand Patil's devotion within his community?

The lasting legacy of Chand Patil's devotion was the establishment and popularization of the 'Satya-Sai vow' in his village. After achieving his goal and returning home, his heart was overflowing with joy and gratitude. As Chapter 13 details, he started performing this new vow regularly with friends, relatives, and brothers. The text explicitly states, 'The Patil started the tradition, and it became the custom in the village.' This led to successive recitations of the 'Satya-Sai vow,' ensuring that the grace of Sai, as experienced by Patil, was shared and perpetuated throughout his community.
