The Opening of the Mouth

vaisvil

The Book of the Dead contains a spell for this process

My mouth is opened by Ptah,
My mouth's bonds are loosed by my city-god.
Thoth has come fully equipped with spells,
He looses the bonds of Seth from my mouth.
Atum has given me my hands,
They are placed as guardians.

My mouth is given to me,
My mouth is opened by Ptah,
With that chisel of metal
With which he opened the mouth of the gods.
I am Sekhmet-Wadjet who dwells in the west of heaven,
I am Sahyt among the souls of On.
