Aleister Crowley lived by The Book of the Law to the end of his days. The true author of that "automatic writing" (a paranormal being), supposedly having certain knowledge of future events, devoted a portion of a versicle (L 2:66) to the "greater feast" (i.e. death) of the scribe:
"Ah! Thy death shall be lovely: whoso seeth it shall be glad. Thy death shall be the seal of the promise of our agelong love. Come! lift up thine heart & rejoice! We are one; we are none."
That last part is the reminder to him that death is not the end it seems to be, because the curve of life through which we slide is an illusion for our play of love, as in truth "we are none".
The celebration of a genius so prolific cannot be confined to a single day. As this is the "greater feast" of the prophet, we find it best to celebrate it all month long. That way, too, it matches up with the solstitial & vulgar new year traditions.
Anyway, not too long of a post here - I just wished to bring up greater Crowleymas, since nobody has mentioned it, and maybe drum up interesting discussion on matters surrounding the death, funeral, ashes, and the aftermath of the death of the prophet.
Happy holidays from the Holy Thelemic Church! 93s to all.
