the beds of Man, robbing the Water of Life and the Food of Life in which to
quicken the Dead, but their labours are fruitless for they do not have

the Water of Life may be brought to call many, for after the passage of
one-tenth of a Moon the Elements are dead. And GELAL invades the bed of a Woman, and LILIT that of a Man, and
sometimes evil beings are born of these hauntings, and as such must be
slain, for the children of GELAL are workers natural of the ANCIENT
ONE, having His Spirit; and the children of LILIT are likewise, but are born
in secret places which may not be perceived by Man, and it is not until
the time of their maturity that such as these are given to walking in
the places of Men.And GELAL rideth upon the Wind, but oftentimes LILIT cometh of the
Water. Which is why running Water must be used in the Rites, because of
the cleanliness thereof.
And the sign of the GELAL is thus:
