Atbash

From Innerpedia

At-bash (אתב"ש) is a basic "reflective" transformation pattern, wherein the first and last letters of the alef-beit transform into one another, as do the second and second-to-last, and so on.

The name At-bash is a reference to the first two of these transformation pairs: alef-tav and beit-shin.

At-bash is the alphabetic transformation whose elements correspond to the sefirot within the partzuf of Imma or the sefirah of understanding.
