The Oera Linda Book, by Wiliam R. Sandbach, , at sacred-texts.com
All the regulations which have existed a century, that is, a hundred years, may by the advice of the Eeremoeder, with the consent of the community, be inscribed upon the walls of the citadel, and when inscribed on the walls they become laws, and it is our duty to respect them all. If by force or necessity any regulations should be imposed upon ne at variance with our laws and customs, we must submit; but should we be released, we must always return to our own again. That is Frya's will, and must be that of all her children.
p. 24 p. 25
Anything that any man commences, whatever it may be, on the day appointed for Frya's worship shall eternally fail, for time has proved that she was right; and it is become a law that no man shall, except from absolute necessity, keep that day otherwise than as a joyful feast.
