How was Sai Baba's Udi shown to be an effective remedy for insomnia, based on the accounts in the Satcharita?

Chapter 33 provides two compelling anecdotes demonstrating how Udi was used to cure sleep-related problems. The first account, shared by R. Hari Sitaram Dixit, involves his friend who had been unable to sleep for eight days, even with a doctor's medicine. Dixit gave him some of Baba's Udi and instructed him to take it. As Chapter 33 notes, the very next day, the friend reported that he had taken the Udi and slept soundly through the entire night. A second, similar case involved a friend's child in Bandra who had not been able to sleep for two months. The father took the child to Shirdi for Maharaj's Darshan. That very same night, the child got sleep, and the issue was resolved permanently from then on, showcasing the immediate and powerful effect of Baba's grace and Udi.
