Acharya Prashant explains that behavior is essentially action that can be sensed, such as speaking or physical gestures. He clarifies that these actions originate from two distinct sources: mechanical conditioning or understanding. He defines attitude as a pre-formed opinion, bias, or prejudice carried over from the past. This frozen state of mind prevents a person from seeing things as they are in the present moment. In contrast, understanding is the process of knowing something exactly as it is right now. Because attitude relies on the past and understanding occurs in the present, the two are fundamentally opposite and cannot coexist; any attitude, whether positive or negative, acts as an obstacle to understanding by freezing the mind's fluidity.
