Don't let grief vex you. You should let it into your heart. Nor should you be afraid of madness. It comes to you perhaps as a friend and not as an enemy, and the only thing that is bad is your resistance. Let grief into your heart. Don't lock the door on it. Standing outside the door, in the mind, it is frightening, but in the heart it is not.
