" Since flow is a fluid action state, making better decisions isn’t enough: we also have to act on those decisions. The problem is fear, which stands between us and all actions. Yet our fears are grounded in self, time, and space. With our sense of self out of the way we are liberated from doubt and insecurity. With time gone, there is no yesterday to regret or tomorrow to worry about. And when our sense of space disappears, so do physical consequences. But when all three vanish at once, something far more incredible occurs: our fear of death—that most fundamental of all fears—can no longer exist. Simply put: if you’re infinite and atemporal, you cannot die. "
