Acharya Prashant advises that to overcome the fear and overthinking associated with everyday situations, one must think of better and more important things. He suggests having something in life that is so powerful it overpowers all random thoughts. Using himself as an example, he explains that despite being a busy person with many alternative thoughts available, he focuses on the conversation at hand because it is important. This importance makes him forget all other things. When you do not have something truly important in your life, a lot of little things will invade the mind. The speaker compares these random thoughts to germs, which are impossible to keep away entirely. The only solution is to develop a strong inner immunity. This inner immunity is the sense of what is worthy and important. When you lack a sense of the worthy, there is an inner vacancy that gets filled with trivial matters, as the mind cannot tolerate a vacuum and needs something to chew on. The result of not having something important is that a lot of little things will invade the mind, and there is no way to keep them away. For students and beginners, the path is to determine what is important, give it due credit, fall in love with it, and make it their life. This immersion leaves no space for random thoughts. He illustrates this with the example of Bhagat Singh, who was so occupied with his mission for freedom that he had no time for miscellaneous thoughts, fear, or anxiety, even in his final moments. He was wedded to 'Azadi' (Freedom). When death came, he was still reading the Bhagavad Gita, so immersed that he had to be prodded to proceed. Acharya Prashant concludes that having one thing worth living for is the antidote to all mental troubles. When you are occupied with something truly important, you have no time to be anxious and no space for fear. This state of immersion is the best meditation. If you are not immersed, you are scattered. Most people waste their entire lives being busy with nothing in particular. The one who has something to live for will never be mentally sick, as their life is not devoid of essence.
