The Feast of Thanksgiving Offerings and the Establishment of the Celestial Cow, which we sometimes call "Moo-mas" for fun, begins 25 December.
Establishing the Celestial Cow
Feast of Thanksgiving Offerings
Djehuty sends Bast and Sekhmet to guard the Two Lands
Two great goddesses come forth from the Keeper of Wisdom (on that day) to protect us and keep us safe. Bast and Sekhmet, Ra's Eyes, mighty lionesses Who guard and guide, preside over this holy day and honor us with Their special presences. Make offerings to all three with prayers for protection and guidance as the Gregorian year makes another turn.
Celebrate! The anniversary of Hethert, the Great Cow, becoming Nut, the multitudinous sky, is upon us! Greet Her in the starlight and Her Father, Ra, in sunlight, as Day Sky and Night Sky become one! Offer honey and warm drinks to Her, to sweeten Her disposition toward you, and to bring the prosperity of the starry heavens into your life. It is also a time for merriment and gift-giving.
The Festival of Establishing the Celestial Cow and Placing Offerings Upon the Altar
This long name says it all -- (this is) a three-day festival of gift-giving upon the return of Hethert-Sekhmet to our land, as observed in the lengthening of the days in the Northern Hemisphere where Egypt lies. However, unlike Kemetic New Year where the emphasis is upon giving gifts to each other, the Celestial Cow/Feast of Offerings days are geared toward giving gifts to Netjer, and Netjer's House in the form of gifts to our temple and temple community.
