Is it really true that spiritual goals are impossible without 'shraddha' and 'saburi'? Couldn't one achieve them through intellect and debate alone?

According to the author Hemadpant's personal experience detailed in Chapter 2, intellect and debating are actually detrimental to spiritual progress. He was specifically given a lesson to destroy his pride in debating, which he came to see as an "extremely harmful" trait. He learned that competing with others and engaging in arguments should be avoided. The text firmly asserts the scriptural truth that "Without faith (Shraddha) and patience (Saburi), Not a bit of the spiritual goal is achieved." This principle is presented as an unwavering truth, experienced by the author himself, placing these qualities far above intellectual debate for attaining spiritual knowledge.
