The story of the four who entered pardes, or the orchard, is the crux interpretum of the study of ancient Jewish mysticism. The answer to the question of how much mysticism existed in rabbinic Judaism depends on the interpretation of this story. In the history of scholarship of the past several decades, two major approaches have been taken. One approach, spearheaded by Gershom Scholem, although by no means initiated by him, sees in this story a record or some testimony of a mystical experience. The various terms employed, and in particular the term pardes, are seen as expressive of a heavenly ascent into paradise, and thus as a testimony of a mystical experience. The other approach, which consciously seeks to tone down the mystical and ecstatic element of the pardes story, sees in this story a parable. If it is a parable, then we do not have a record or testimony of an event of a mystical nature. Of course, even if the story is parabolic, the question of the subject of the parable remains open. Ephraim E. Urbach, who first took this line of interpretation, suggested that the story is a parable, and not a mystical record. The story refers, however, to the study of maʿaseh merkabah (“the work or story of the divine chariot,” referred to in the first chapter of Ezekiel), and thus retains esoteric significance.
