Acharya Prashant explains that while traditional superstitions like ghosts and magic have faded due to science, a new form of superstition persists through lack of faith and understanding. He defines superstition as believing in something without knowing or understanding it. Today, people blindly trust their careers and societal norms without true comprehension, which is essentially the same phenomenon in a modern guise. He asserts that the only remedy for superstition is faith, which he equates with deep knowledge and the wisdom to distinguish between the illusory and the real.
