Acharya Prashant addresses a question about a couplet by Kabir Saheb: "Everyone says 'maya, maya', but no one understands it. That which does not leave the mind, call that maya." The questioner asks if even good thoughts that persist in the mind are considered 'maya'. Acharya Prashant explains that there is a fundamental difference between a good thought ('suvichar') and a bad thought ('kuvichar'). A bad thought is an effort by the thinker, the ego, to save itself. This thinker within us is false and hollow, and its effort to preserve itself is what is called a bad thought. The nature of a bad thought is that it is repetitive and circular, like a stuck gramophone record. It doesn't lead to any real outcome or essence; it just keeps rotating. It's like a mosquito buzzing around your head, not saying anything new, just buzzing. Its purpose is to keep the mind busy, waste time, and prevent any real change in life. In contrast, a good thought ('suvichar') is the thinker's effort to dissolve itself. It is the thinker's desire to be removed or to merge. A good thought will not just linger in the mind; it will fill you with energy and compel you to change your life. Once its work is done, it leaves. This directly relates to Kabir's couplet, as a good thought will not remain on the mind. The thought that doesn't leave, that just keeps revolving, is the bad thought, and that is 'maya'. The speaker clarifies that when one says "my thought" or "I am thinking," the thinker, the ego, is present. We have the choice of which thoughts to entertain and should not give hospitality to useless, repetitive thoughts. A thought is beneficial if it leads to progress and betterment in life. If it only revolves without producing any result, it is a harmful thought. The speaker also addresses the questioner's point about the thinker's existence. He explains that when you say "my thought," you are acknowledging the thinker. The thinker is the "I" or "me." He further explains that the ego never wants to be hurt and will do anything to protect itself. However, the one who is ready to be hurt for the sake of truth is the one who can transcend the ego. The ego's existence is a wound in itself, and the one who knows this is ready to get hurt to heal it. The choice is always available to us whether to let a thought remain or to let it go. A good thought will come, bring about a change, and then leave.
