Acharya Prashant explains that every belief is destined to break because belief is essentially accepting something without knowing or understanding it. He categorizes belief into two types: the first comes from others, where one accepts something simply because everyone else says so, which is often blind faith. The second type is based on one's own feelings or intellect, but even this is flawed because our feelings and preferences are conditioned by social influences and past impressions. Since these beliefs are not rooted in reality, they inevitably collapse when confronted with the truth, leading to pain and suffering.
