On the Oral Transmission
“On the other hand it would be a mistake to overlook the possibility that such an esoteric conception of the symbols of the Merkabah in the spirit of the Book Bahir might be found in the writings of Eleazar of Worms, especially as he refers to an oral tradition concerning the mystical significance of such symbols.
“When it is said in the book of the Merkabah that the angels who are placed over the doors of the seven Hekhaloth ride fiery horses that eat fiery coals. . . . It is well known that there is no eating and drinking in the supernal regions. But if I were to write down the interpretation, someone who is not worthy might see it and arrive at corrupt conceptions of it. . . . That is why [such an interpretation can be transmitted] only by way of tradition, kabbalah, that is to say, through oral transmission.”
The first kabbalists also interpreted the prophets’ descriptions of the Merkabah and the revelations of the authors of the Hekhaloth literature as symbols of profoundly spiritual states. It is not without reason that the anonymous kabbalistic commentary on the Merkabah, whose true author can be identified as Jacob ben Cohen of Soria, is attributed in some manuscripts to “the Kabbalah of the Hasid R. Eliezer of Worms.”
In Narbonne around 1250, Jacob Cohen and his brother Isaac met a “Hasid and kabbalist,” a pupil of Eleazar, who apparently knew how to combine the Hasidic tradition with the kabbalistic tradition of the Provençal group. Perhaps this anonymous disciple was more loyal to the oral transmission of his teacher’s ideas than we are able to conclude from a simple comparison of his writings with those of the earliest kabbalists.”
