The word for garden in Hebrew is Pardes. The root is P-R-D-S. It is taught that there are four ways to read and explore the scripture. The basic approach is Pshat, which means literal. Another way is Remez, which means a hint and is the metaphorical understanding. The third is Drosh, which is the analytical approach in which different parts of the scripture are brought to explain each other. Finally is the Sod, which means the secret approach, which is unwrapping the codes that explain the scripture. The sod makes up the body of the Kabbalah.
