What is Sai Baba's perspective on argumentation and ego in the context of spiritual growth?

Sai Baba's guidance, as detailed in Chapter 2, is very clear on the detrimental effects of ego and argumentation on the spiritual path. He advises, "Do not engage in dualistic explanations," calling such debates useless effort. The text warns that where there is a mind for argumentation, there is an abundance of ignorance and Maya, and such a person is not fit for self-knowledge. In contrast, Baba emphasizes the necessity of dissolving the ego and surrendering it at His feet. He promises that for one who achieves this, He will provide full assistance, stating, "When the ego is dissolved...I myself shall enter with 'I-ness' and write with my own hand."
