Acharya Prashant begins by defining a positive thought as one that makes you happy, is about your well-being, or is a thought of hope. However, he explains that hope is never certain and is always accompanied by fear. When you hope that you might win, you are also somewhere afraid that you might not, so uncertainty is always there. Being positive is like looking at one side of a coin, but deep within, you know that the other side also exists and is just waiting to show up. A little flip and everything would change. Consequently, thought never gives you total assurance. You remain a bit iffy, and everything remains dicey. You cannot fully relax or just go to sleep. It always remains important, therefore, to carry your defenses. With thought, fear is always present. First of all, fear is there, and second, a continuation of thought is there. When something has not been concluded, it would continue, and with thought, there is never any conclusion. Therefore, an indefinite continuation is there. You keep thinking, and it is like an infinite snakes and ladders game. Just when you think that you are about to reach the conclusion, you land in the mouth of a giant snake and you are back to square one. This process helps you to while away life. Thought serves a great purpose: it eats away your time. Otherwise, time will become such a burden. By thinking continuously, you comfortably let days, months, years, and decades slip away. Then you are so thankful that death arrives; otherwise, living 80 years in awareness would have been such a pain. Thought facilitates an avoidance of right action. For instance, if someone demands that you climb a hill, you can say, "No, I'm still thinking." All the effort and pain that would have come with climbing the hill has been successfully avoided because you are still thinking. Thinking is nice; scaling the heights is arduous. The speaker concludes by posing a question: if a positive thought is really positive, why are there ever any negative thoughts after it? A truly positive thought should have ended even the possibility of any future negativity, but that possibility always remains.
