A wondercafe poster has been explaining scripture in a very unique way. She has a lot of experience with Judaism, and the way it looks at the Bible is very refreshing. She sent me the following info:
It is PaRDeS. like a dreidel the letters are initials. They stand for Peshat, Remez, Derash, Sod.
Peshat = the surface meaning
Remez = allusions or allegories
Derash = midrash way of finding new lessons
Sod = the hidden mystical Kabbalah way
