The words Sator, Arepo, Tenet, Opera, and Rotas are written out as a square (Arepo under Sator, Tenet under Arepo, and so on), so it can be read left to right, but also up and down. It’s also a palindrome, meaning the phrase is the same backward.
“Write out the square on a piece of paper, while envisioning yourself surrounded by a circle of protection,” Lyons says. It should look something like this:
S A T O R
A R E P O
T E N E T
O P E R A
R O T A S
When you are done, chant the words ‘Sator, Arepo, Tenet, Opera, Rotas’ to charge the paper. Carry it with you for protection from harm and repeat the chant as necessary.
