It's one of those things that's in Btetz et al at PGM XIII 824-841
same book for Mithras Liturgy (The most widely read of all the PGM)
You can also see it in slightly amended form in Steven Flower's interesting
'Hermetic Magick: the postmodern Magical Papyrus of Abaris'
Its also recommended n my own book
'Tankhem: Seth and Egyptian Magick'
and probably elsewhere - because of the seven fold nature of the rite -
it is currently been revived by several 'sethian' and 'sabbatic groups
instead of the LBR -
although the whole business about the symbolism of the number seven, the
starry plough etc., is something whose significance is spreading to most
'love and do what you will'
