The text advises against argumentation and refuting others, stating 'Do not engage in dualistic explanations.' Isn't this just a tactic to shut down critical thinking and prevent people from questioning the book's claims?

The text presents this guidance as a spiritual instruction rather than a method to suppress intellectual inquiry. As explained in Chapter 2, a mind inclined toward argumentation is seen as a sign of abundant ignorance and Maya, which are obstacles to attaining self-knowledge. Such a mind, filled with "bad thoughts and false logic," is considered unfit for the spiritual path and leads only to unhappiness. The advice to avoid refuting others or establishing one's own side is described as avoiding "useless effort." The goal is to steer the seeker away from dualistic debates and toward devotion and faith, which are presented as the direct means to experience self-bliss and divine harmony.
