Could you elaborate on how Chand Patil demonstrated his devotion to Sai Baba after his illness was cured?

Chand Patil's devotion after his healing was profound and multifaceted. According to Chapter 13, immediately after being cured, he sought Baba's darshan, where his ocean of joy overflowed, and he wept tears of love, placing his forehead on Baba's feet in total surrender. He then stayed in Shirdi for a month and continued to visit frequently thereafter, his heart filled with faith and gratitude. His most significant devotional act was establishing the 'Satya-Sai vow,' a weekly ritual where he would read the three chapters on Sainath from Das Ganu's 'Bhaktalilamrut,' a practice that brought him immense peace.
