In this episode, Krishna says that human mind is always encircled with fear. Humans have an inborn fear because they care. They care about their families and their well-being. They care about their professional work and its results. They all want to pass that dreadful admissions exam, be promoted to a better position, and receive that loan to start a new business venture. Every one thinks that fear is a part of human nature. Somewhere deep down, they all just want to succeed. The desire for success, however, sometimes comes attached with the debilitating fear of failure. But Krishna says that fear is nothing but the imagination of future which is going to come, and the future results are not going to be according to our thoughts and imaginations, so why to worry then. Neither we can create future nor we can see it, we have no control over the future. So be fearful and do your duties.
