This is from Scott Cunningham's Wicca: A Guide for the Solitary Practitioner. I've been noticing that as I get older and more settled into my practices, I've been going back to a lot of his work. The simplicity and meaning of his rituals are something of great beauty. I believe more people should go over his work again, there are quite a few gems to be found!
Place upon the altar sheaves of wheat, barley or oats, fruit and breads, perhaps a loaf fashioned in the figure of the Sun or a man to represent the God. Corn dollies, symbolic of the goddess, can be present there as well.
Arrange the altar, light the candles and censer, and
cast the Circle of Stones.
Recite the Blessing Chant.
Invoke the Goddess and God.
Stand before the altar, holding aloft the sheaves of grain, saying these or similar words:
"Now is the time of the First Harvest,
when bounties of nature give of themselves
so that we may survive.
O God of the ripening fields, Lord of the Grain,
grant me the understanding of sacrifice as you
prepare to deliver yourself under the sickle of the
goddess and journey to the lands of eternal summer.
O Goddess of the Dark Moon,
teach me the secrets of rebirth
as the Sun loses its strength and the nights grow cold."
Rub the heads of the wheat with your fingers so that the grains fall onto the altar. Lift a piece of fruit and bit, savouring it flavour, and say:
"I partake of the first harvest, mixing its energies
with mine that I may continue my quest for the starry
wisdom of perfection.
O Lady of the Moon and Lord of the Sun,
gracious ones before Whom the stars halt their courses,
I offer my thanks for the continuing fertility of the Earth.
May the nodding grain loose its seeds to be buried in
the Mother’s breast, ensuring rebirth in the warmth
of the coming Spring."
Consume the rest of the fruit.
Works of magic, if necessary, may follow.
Celebrate the Simple Feast.
The circle is released.
