What is Sai Baba's philosophy regarding argumentation, ego, and their impact on achieving self-knowledge?

Sai Baba's philosophy, as presented in Chapter 2, strongly advises against ego and argumentation on the spiritual path. He teaches that where there is a mind for argumentation, there is an abundance of ignorance and Maya, leading to bad thoughts and false logic. Such a person is deemed unfit for self-knowledge and is destined for unhappiness. The key to progress is to dissolve the ego and surrender it at His feet. He explicitly counsels against establishing one's own side or refuting others, calling such 'dualistic explanations' a useless effort. True bliss and knowledge come from faith and devotion, not intellectual debate.
