What do you do that makes you feel invincible?

I think meditation brings me closest to this feeling. When I meditate, it really puts things into perspective. I remember that there really isn't a such thing as defeat. So, in this way, I feel invincible. When I meditate, I slow down enough to get beyond duality and labels. I remind myself that I create my own life, for better or worse. And once I remember that, it gives me a great sense of control. I may not control everything that happens to me, but I certainly control how I react and the choices I make each day. That's a very liberating feeling, which has a tendency to make one feel invincible!
