A kind of occult theosophy or traditional interpretation of
the Scriptures among Jewish rabbis and certain mediaeval Christians,
which treats of the nature of god and the mystery of human existence.
It assumes that every letter, word, number, and accent of Scripture
contains a hidden sense; and it teaches the methods of interpretation
for ascertaining these occult meanings. The cabalists pretend even to
foretell events by this means.

Secret science in general; mystic art; mystery.
