"Perfect love casts out fear." It is not be thinking ourselve sright that we cease to fear. It is simply by loving, and abandoning ourselves to the One whom we love without returning to self. That is what makes death sweet and precious. When we are dead to ourselves, the death of the body is only the consummation of the work of grace.
Sean, my Yogic Irish dairy farmer, explained our chaotic world to me in this way. "Imagine that the universe is a great spinning engine," he said. "You want to stay near the core of the thing -- right in the hub of the wheel -- not out at the edges where all the wild whirling takes place, where you can get frayed and crazy. The hub of calmness -- that's your heart. That’s where God lives within you. So stop looking for answers in the world. Just keep coming back to that center and you'll always find peace."
