Acharya Prashant explains that the fear of the unknown is actually rooted in ignorance of the known. People often hesitate to enter the unknown because they have a false sense of security or faith in the known, despite the fact that the known—such as familiar people, one's own body, or current circumstances—is often the source of their greatest suffering and deception. He points out that we are more likely to be harmed by familiar diseases or people we know than by strangers or the unknown. Therefore, if one truly understands the nature of the known and sees that it offers no real peace or joy, the unknown will no longer seem frightening; instead, one will become eager to move beyond the current limited circle of existence.
