In surrender, you no longer need ego defenses and false masks. You become very simple, very real. "That's dangerous," says the ego. "You'll get hurt. You'll become vulnerable." What the ego doesn't know, of course, is that only through the letting go of resistance, through becoming "vulnerable," can you discover your true and essential invulnerability.
