Greetings of the September (Southward) Equinox, when the sun crosses the projection of the earth’s equator (at 180° ecliptic longitude) into the southern hemisphere, and enters the sign of Libra, the Cardinal Sign of Air.
According to NOAA, it is the beginning of astronomical autumn in the Northern Hemisphere, although meteorological autumn begins on September 1. It is, thus, typically referred to as the “autumnal equinox” in the Northern Hemisphere. Some traditions hold that the autumnal equinox is not autumn’s beginning, but its midpoint; with the cross-quarter point in August being its beginning.
The moment of Equinox occurs early tomorrow morning at 07:50 UTC, which is 12:50 AM PDT for those of us on the West Coast and 3:50 AM EDT for those on the East Coast.
“There are rituals of the elements and feasts of the times.“AL II:36
Each element — fire, earth, air, water, and Spirit — possesses its own Nature, Will, and Magical Formula. Each one may then have its appropriate ritual. Many such in crude form are described in The Golden Bough of Dr. J.G. Frazer, the Glory of Trinity!
In particular the entry of the Sun into the cardinal signs of the elements at the Equinoxes and Solstices are suitable for festivals.
The difference between ‘rituals’ and ‘feasts’ is this: by the one a particular form of energy is generated, while there is a general discharge of one’s superfluous force in the other. Yet a feast implies periodical nourishment.Crowley’s “New Comment” on AL II:36
