What is Sai Baba's perspective on argumentation versus faith, and what is the role of the ego in spiritual progress?

According to the teachings in Chapter 2, there is a stark contrast between argumentation and faith. Sai Baba advises against engaging in dualistic explanations or refuting others, viewing such efforts as useless. The text states that a mind inclined towards argumentation is filled with ignorance, Maya, and false logic, making one unfit for self-knowledge and leading only to unhappiness. Conversely, true spiritual progress requires the dissolution of the ego. Baba insisted that the author must surrender his ego at his feet. Only then would Baba himself enter and write the stories, providing full assistance and ensuring the work's success. This highlights that faith and surrender are paramount, while ego and debate are obstacles.
