Acharya Prashant explains that one should not fight with mental tendencies ('vrittis'), because the one who tries to fight a tendency is another tendency. He states that it is sufficient to simply know that a tendency has arisen. The one who fights a tendency is another tendency, but intelligence is a non-doer. Intelligence does not do anything; it only knows. In this very knowing, the right action automatically happens. The speaker clarifies that one will not know the right action in advance. If one knows the action beforehand, it becomes a calculated, planned action, which is no longer spontaneous. Intelligence is all about spontaneity. The advice is to simply know and let the spontaneous action happen. When one feels that the mind is playing tricks, it is the ego, the 'me', that is at play. One should observe the entire game without impatience or an urge to act. The core principle is that knowing is sufficient. After knowing, one should not keep checking for results. Instead, one should just know and have faith. Faith is the understanding that there is something ultimate and unshakable that one can depend on. Faith cannot be placed in any 'thing', as all things are transient. The mind is restless by nature, and the way to deal with it is not to stop it but to remain with it, which means to keep observing it. The mind changes under observation. Whether it is fear or any other tendency, the task is to see it as it is. Knowing is sufficient, and one must have faith.
