כ"ט טבת ה'תשס"ז
In the previous entry discussing Dark Moon consecration of my athame, the (tips of the) index and middle fingers of the right hand will be used in tonight's ritual. Luis and Fearn are the two letters of the Ogham which correspond to the two ritual fingers.
Celtic luis (L) and fearn (F) correspond to Hebrew (ל) lamed and (ו) vav , respectively. The combined gematria of lamed-vav (לו) is 36. Thus, the two fingers of the right hand used in the ritual represent the completely righteous "revealed 36", while these two fingers of the left hand represent the completely righteous "concealed 36", for a total of 72.
