Arjuna voices something every human being has felt. You know what is right. You even want to do what is right. And yet something inside drags you the other way, almost as if by force. What is that power? Where does it live? Who is pulling the strings?
The phrase 'anichchhann api' (even without wanting to) is painfully honest. This is not about deliberate wrongdoing. It is about the baffling experience of acting against your own better judgment. Arjuna gives this inner hijacker a vivid image: it is as though someone is forcing you.
