“In the history of Jewish literature, Nahmanides is often considered to exemplify the “most Jewish” spirit; he was the one among Spanish Jews who expressed the deepest convictions regarding the Judaism of his time and embodied what was best and highest in it. From the point of view of a “refined” Judaism or the pure halakhah, it must indeed appear as an aberration that so clear a mind, one that easily penetrated the most complicated halakhic problems, should have become involved with the Kabbalah.
But it is precisely this dimension of his personality that must be grasped if we wish to understand the phenomenon. Without the Kabbalah and its contemplative mysticism Nahmanides, would be as little understood in his Jewish context as would, in the Christian context, a man like Ramón Lull (who was active in Catalonia a generation later and whose teaching exhibited structurally many analogies with the doctrine of the sefiroth) if one ignored his Ars contemplativa, in which his Christianity reached its culmination, and judged him solely on the basis of his wide-ranging activities in all other possible domains.
From this point of view, Nahmanides’ commentary on Yesirah, which develops his conception of God, is of particular importance. The gnostic doctrine of the aeons and the Neoplatonic doctrine of the emanation are combined, and we see how well they harmonize with a Jewish consciousness.
The monotheism of Nahmanides, the Jewish coloration of which is certainly beyond question, is unaware of any contradiction between the unity of God and its manifestation in the different sefiroth, each of which represents one of the aspects by which the kabhod of God reveals itself to the Shekhinah.
In his commentary on the Torah, in which he had to deal only with God’s activity in His creation, making use of the symbols of theosophy, Nahmanides could avoid touching upon this crucial point; he only discussed it in this document intended for kabbalists.
From whom Nahmanides actually received the esoteric tradition is an open question. He does mention, in his commentary on Yesirah, the Hasid Isaac the Blind, but not as his master. Nor does the letter that Isaac sent to him and to his cousin Jonah Gerondi, of whom we shall have occasion to speak later, indicate any direct discipleship.
Nahmanides refers to Yehudah ben Yaqar as his master, especially in the halakhic writings. Contrariwise, in a series of undoubtedly genuine traditions going back to Nahmanides’ most important disciple, Solomon ibn Adreth, there emerges the thoroughly enigmatic figure of a kabbalist by the name of ben Belimah—the personal first name is never mentioned—who is said to have been the connecting link between him and Isaac the Blind.
Meir ibn Sahula, in his commentaries on the traditions of Nahmanides (fol. 29a), contrasts those he had received from ben Belimah with those deriving from Isaac. In very old marginal notes emanating from the circle of Gerona and preserved in Ms. Parma, de Rossi 68, mention is made of a debate between Nahmanides and ben Belimah over the fate of Naboth’s spirit (1 Kings 22); the debate suggests that ben Belimah posited some kind of transmigration of souls or metamorphosis also for the higher spirits, even within the world of the sefiroth up to binah.
The existence of such a kabbalist therefore seems established beyond doubt, no matter how enigmatic his name. It is neither a family name nor a patronymic. Belimah is not known to me as a woman’s name, and it is extremely unlikely that Solomon ibn Adreth would have transmitted the name in a corrupted form to his disciples.
There remains the hypothesis of a pseudonym deliberately substituted for another name that was kept secret for reasons unknown to us and in a manner completely contrary to the habit of this circle. The pseudonym seems to be derived from B. Hullin 89a, where Job 26:7 is applied to Moses and Aaron who, when assailed by the Israelites, changed themselves into nothing!
The kabbalist in question thus may possibly have been a [ . . . ] ben Moses (rather than [ . . . ] ben Aaron). B. Dinur’s suggestion that the pseudonym refers to R. Jonah ben Abraham Gerondi (because of his attitude in the Maimonidean controversy) seems improbable. Perhaps new manuscript discoveries will one day clarify matters.
In any case, this name, whose literal translation would be “son of the Nought” or “son of seclusion,” provokes the historian’s curiosity. It remains uncertain whether ben Belimah should be located in Gerona, which is quite possible, or in Provence, where Nahmanides could have met with him during his youth.”
