But ye, o my people, rise up & awake! Let the rituals be rightly performed with joy & beauty! There are rituals of the elements and feasts of the times. A feast for the first night of the Prophet and his Bride! A feast for the three days of the writing of the Book of the Law. A feast for Tahuti and the child of the Prophet--secret, O Prophet! A feast for the Supreme Ritual, and a feast for the Equinox of the Gods. A feast for fire and a feast for water; a feast for life and a greater feast for death! A feast every day in your hearts in the joy of my rapture! A feast every night unto Nu, and the pleasure of uttermost delight! Aye! feast! rejoice! there is no dread hereafter. There is the dissolution, and eternal ecstasy in the kisses of Nu. ~ Liber AL II: 34-44 ~
The Thelemic Holy Season begins the night before the Vernal or Spring Equinox (what is referred to by Thelemites as "The Equinox of the Gods" and the "Supreme Ritual") and continues for 22 days, culminating in the Three Days of the Writing of the Book of the Law on April 8, 9 and 10 of each year.
Each of the twenty-two days of the Thelemic Holy Season is attributed by many Thelemites to one of the 22 letters of the Hebrew alphabet. Frequently aspirants, on each of these days, prominently display the corresponding Tarot Trump, and conduct such other meditation, ritual, or other recognition of the principle as they may see fit. In the list below are also given recommended readings from the sacred writings for each day of the Holy Season.
On the night before the Vernal Equinox, closing the old year (usually March 19), it is recommended that the aspirant read The Prologue of the Unborn from Liber VII and meditate on the release of the concluding cycle.
On March 20, the Invocation of Horus (The Supreme Ritual) may be performed to celebrate the anniversary of the Equinox of the Gods. The following readings (most, but not all, of which are from "Holy Books of Thelema") are then recommended for each of the 22 days.
In addition to the 22 days of the Holy Season, the following holidays are celebrated throughout the year.
August 12 ~ The First Night of the Prophet and His Bride Birth (Feast for Life), Coming of Age (Feast for Fire/Water) and Death (Greater Feast) Equinoxes and Solstices Cross-Quarter Celebrations
I am the Heart; and the Snake is entwined About the invisible core of the mind. Rise, O my snake! It is now is the hour Of the hooded and holy ineffable flower. Rise, O my snake, into brilliance of bloom On the corpse of Osiris afloat in the tomb! O heart of my mother, my sister, mine own, Thou art given to Nile, to the terror Typhon! Ah me! but the glory of ravening storm Enswathes thee and wraps thee in frenzy of form. Be still, O my soul! that the spell may dissolve As the wands are upraised, and the aeons revolve. Behold! in my beauty how joyous Thou art, O Snake that caresses the crown of mine heart! Behold! we are one, and the tempest of years Goes down to the dusk, and the Beetle appears. O Beetle! the drone of Thy dolorous note Be ever the trance of this tremulous throat! I await the awaking! The summons on high From the Lord Adonai, from the Lord Adonai! ~ Liber Cordis Cincti Serpente I:1 ~
