My friend is very analytical and skeptical about spirituality. How did Sai Baba deal with people who came to him with a 'clinical interest' or doubts?

Sai Baba had a unique way of transforming skeptics into devotees, as illustrated by the story of Boss Dharamsee. Chapter 35 explains that Dharamsee arrived in Shirdi with a 'clinical scrutiny' and was critical from the start. He mentally questioned Baba's sainthood when offered grapes with seeds, which he disliked. Baba, knowing his inner thoughts, first gave him more of the disliked grapes, then commanded him to eat them. When Dharamsee obeyed, he found the grapes had miraculously become seedless. This direct experience shattered his ego and skepticism, replacing it with love and a firm determination to follow Sai. This shows that Baba often works on individuals not through discourse, but through personal experiences that address their specific doubts and disposition.
