Can intellectualism and debate lead to spiritual success? What does Baba say is the more effective path?

No, intellectualism and debate are not the path to spiritual success. Chapter 17 is very clear on this, stating that logic and debate do not work, nor do repetitions or rumors. It is taught that the cleverness of logic does not apply, and in fact, the mind of the logician becomes blunt. The text emphasizes that success will only be found through God's grace and that other arguments are useless. Instead of complex reasoning, the teachings highlight that simple devotion is what succeeds. This is considered a wonder, as the cause of perfect knowledge is a different path and a different intellect altogether.
