Acharya Prashant explains the importance of being cautious about what one consumes, not just physically but also mentally. He begins with an analogy, stating that while people are careful enough to peel a banana or wash and cook vegetables before eating, they indiscriminately swallow anyone's words. They consume ideas without checking if they are rotten, infested with worms, or covered in filth. This lack of scrutiny in mental consumption is a grave error. He emphasizes that treating a physical illness is far easier than curing a polluted mind. If someone drinks contaminated water, medicine can provide a cure. However, if one listens to 'dirty words' (gandi baani), the speaker questions who will be able to save them. Therefore, he urges extreme vigilance regarding what enters the mind through the ears and eyes. One must be very alert about the words they allow themselves to hear and not fall for the notion that there is no harm in just listening. Acharya Prashant strongly refutes the common saying, 'Listen to everyone, but do what your mind says.' He argues that listening is not a passive act over which one has complete control. Without realizing it, a person gets carried away by what they hear. What you listen to, you become; the words you hear continuously take over your mind. He compares this to breathing polluted air, which inevitably harms the lungs. Similarly, listening to filthy words will undoubtedly affect the mind. He concludes that the principle of 'listening to everyone' is dangerous because you become a slave to whomever you listen to. Instead of doing what the mind says, one should do what the Truth (Rab) says, because the mind itself is merely a product of everything it has heard. Thus, the saying 'Listen to everyone, do what your mind says' effectively means 'Listen to everyone, and then do what you have heard.' He advises against listening to everything unless one has attained such a powerful state of understanding and unwavering faith that nothing can affect them, a state he implies the listener has not yet reached.
