Anxiety - a feeling you should immediately react against

"You are busy with one thing or another, and all of a sudden you feel a sense of darkness, emptiness, loneliness, and you are filled with anxiety… Be aware that this is an intruder trying to sneak its way into you, or else your consciousness has gone travelling and lost itself in a hostile region, for that can happen too, and to anyone.

When you have such a feeling, don’t just stay there and do nothing; react, because that feeling opens the door, as it were, to much more serious events which will automatically follow. Take a look within immediately to see what has brought you to this place. Then, through prayer and meditation, try to return to the path that will take you in among the spirits of light and peace, and tell them they are the only ones you want to allow into your home."
