According to the provided text, what are the spiritual benefits of listening to Sai Baba's stories, and what kind of mindset is considered a hindrance to spiritual progress?

The source material from Chapter 2 explains that engaging with Sai Baba's stories yields significant spiritual rewards. By hearing, singing, and contemplating these narratives, devotion to Baba is born and ignorance is immediately destroyed. This practice is said to cultivate faith in the hearts of listeners, leading to self-experience, self-bliss, and a state of happiness. Conversely, the text warns against a mind preoccupied with argumentation, which is equated with ignorance and Maya. Baba advises against dualistic explanations and refuting others, describing such a person as unfit for self-knowledge, destined only for unhappiness. This mindset, filled with bad thoughts and false logic, is a major hindrance to spiritual attainment.
