The Guide for the Perplexed is the literary masterpiece of Moses Maimonides, who is considered the greatest Jewish thinker of all time. It compares the rationalism of Aristotle's philosophy from medieval scholars to Christian theologians in order to disclose the sublime mysteries of the divine. Maimonides represents the most wealthy vein of the Merkava school - the school of the prophets devoted to the techniques of ascension into the Holy Chariot of God. The teachings contained in the Guide for the Perplexed were widely used and further developed by many personalities, such as Abraham Abulafia.
