This Invocation is to be made during the course of any ceremony when it is necessary to summon the Watcher to preside over the outer precincts of the Circle or Gate. The sword is to be thrust into the ground, in the Northeast section, but the AGA MASS SSARATU is not necessary lest thou hast not made sacrifice to thine Watcher in space of one moon in which case it is necessary to sacrifice to it anew, whether in the ceremony or at some other.

Raise the Copper Dagger of Inanna of the calling, and declaim the Invocation in a clear voice, be it loud or soft.

IA MASS SSARATU!
I conjure thee by the Fire of Girra
The veils of Sunken Varloorni,
and by the Lights of SHAMMASH.
I call thee here, before me, in visible shadow
In beholdable form, to watch and protect this sacred circle, this Holy Gate of (N.)
May he of the name unspeakable, the number unknowable,
whom no man hath seen at any time,
whom no geometer measureth
whom no wizard hath ever called
CALL THEE HERE NOW!
Rise up, by ANU I summon thee!
Rise up, by ENLIL I summon thee!
Rise up, by ENKI I summon thee!
Cease to be the Sleeper of EGURRA.
Cease to lie unwaking beneath the mountains of KUR.
Rise up, from the pits of ancient holocausts!
Rise up, from the old abyss of NARR MARRATU!
Come, by ANU!
Come, by ENLIL!
Come, by ENKI!

In the name of the covenent, come and rise up before me!
IA MASS SSARATU! IA MASS SSARATU! IA MASS SSARATU ZI KIA KANPA! BARRGOLOMOLONETH KIA! SHTAH!

At this point, the Watcher will come and stand outside the Gate or Circle until such time he is given the license to depart by the striking of the Priest's left hand on the hilt of the sword while pronouncing the formula BARRA MASS SSARATU! BARRA!

Such are the Laws:
Thou mayest not depart thine sacred precincts until the Watcher has given this license, else he will Devour thee. He cares not what he watches, only that he obey the priest!
