Acharya Prashant explains that understanding is difficult to describe in positive terms and is best understood by identifying what it is not. He asserts that belief is the primary enemy of understanding because holding onto preconceived notions or ideas prevents a person from truly listening and receiving new information. If the mind is already filled with a belief, it cannot understand because it is not open to the truth of the present moment. Therefore, understanding is not the same as believing. Furthermore, Acharya Prashant clarifies that understanding is not a process or activity of the mind, such as thinking, analysis, or logic. Unlike scientific or mathematical processes that rely on solving problems through mental effort, understanding requires no doing. It is not a product of mental activity like comparing, dividing, or formulating. Instead, understanding is simply being present and still. He emphasizes that any mental activity or 'doing' actually hinders the state of understanding. He concludes by relating understanding to the concept of attention and intimacy. To understand something, such as a tree or a human being, one must come into complete and close contact with it without the interference of the mind. This state of 'just listening' or being fully present without processing information is what he calls attention. Understanding happens naturally in this environment of attention, where the mind is at peace and no longer engaged in its usual analytical processes.
