Only blessed beeswax candles will give light.
Remember What Happened to Lot's Wife:
"When, during a cold winter night, thunder
will be roaring, causing the mountains to be shaken, then, quick, close doors and windows ... Your eyes must not debase the terrible happening with curious gazing..." (p. 44, Prophecies of La Fraudais).
"Assemble in prayer in front of the Crucifix. Take shelter under the protection of My Most Blessed Mother ... Do not
allow any doubt take its abode in you, about your salvation: the more confident you will be, the more inexpugnable will be the bulwark with which I want to surround you. Keep blessed candles burning; pray the Rosary." (p. 44, ibid).
"...at the time when I shall save My people, it will not be through any power of men." (p. 94).
My children, says the Blessed Virgin, take good notice of my words:
"His mercy would be well disposed to let itself be moved, but so few souls do pray, such a large number outrage Him. My children: pay heed still more:
"The whole earth has to be chastised.
"The most painful part for you, the most sorrowful, will be when, from above in the sky, the sun will have fallen in a lightness place; when the stars
will start grouping together, a multitude of them together. At the beginning of that sign, you will be seriously thinking of the obscuration of the sun.
"My Son's anger will speak out with such a resounding loudness in its thunder, that even within this kingdom, your homes will crumble down.
"During those days of mourning, a new earthquake will take place, lesser than many others, of a lesser strength than in many other
places. The thing will be easy to notice: everything will be shaken up except the piece of furniture on which the wax candle will be burning. You will gather all around it with the Crucifix and my blessed image. This is what
is going to move away from you that terror which, during those days, will cause many a death.
"Here is a proof of my kindness: those who will have served and invoked me properly, and who preserve my blessed image in their home, I will keep harmless together with all their belongings.
"During those three days, I will give protection to their hungering cattle. I will guard them because it will be impossible
to set one single door ajar. The hunger of the animals will be satiated by me, without any food.
"The heat from the sky will be so scorching as to be unbearable, even within your closed up homes. The whole sky will be set to fire, but thunderbolts will not penetrate the homes where there will be light. Do not be afraid."
(March 24, 1881, pp. 234-235, ibid).
"That part [Brittany] will receive blessing
from Heaven. It will be generously protected." (May 18, 1881, p. 236, ibid).
Brittany, the quaking will be felt, but not far away. The lightnings will be weak, and light the roaring of thunder; but darkness will pass over it, after the same manner as throughout the whole of the West." (May 18, 1881, p. 237, ibid).
