and cannot elevate themselves to higher knowledge. The Zohar compares the Mishna (Talmud) with a lowly slave; the Kabbala, on the other hand, with a powerful mistress. The former has to do with inferior matters, with "clean and unclean," with "permitted and prohibited," with "what is and is not fit to be used." As long as this woman rules with her "now pure, at another time impure blood," the union of the Father with the Matrona (God with Israel) cannot take place. In the Messianic period, on the other hand, when the higher knowledge will awake, and gain the ascendency, the Kabbala will once more assert its dominion over the slave (Talmud), as in the time of the lawgiver Moses. The Zohar lastly compares the study of the Talmud with a rugged, unproductive rock which, when struck, gives out scanty drops of water, causing only disputes and discussions. The Kabbala, on the other hand, is like a spring flowing abundantly, to which only a word needs to be spoken to cause it to pour out its refreshing and vivifying contents. When the Zohar or Midrash of Simon bar Yochaï was published, it aroused the greatest wonder among the Kabbalists. They seized upon it with avidity. Moses de Leon received vast multitudes of orders to send copies. The question, whence all at once had come so comprehensive a work of an old teacher of the Mishna, not a trace of which had been known till then, was thus answered: Nachmani had exhumed it in Palestine, had sent it to his son in Catalonia, by a whirlwind it had been carried to Aragon or Alicante (Valencia), where it had fallen into the hands of Moses de Leon, who alone possessed the original document. The repute of the newly discovered Kabbalistic treasure soon spread through the whole of Spain. The school of Abulafia at once gave the Zohar the tribute of its acknowledgment, and considered it indisputably genuine. Moses de Leon's wildest hopes were more than realized. There were, of course, Kabbalists who doubted that the Zohar had originated with Simon bar Yochaï and his school, but none the less did they pay homage to the book as to a pure source for Kabbalistic theories. When the Kabbalist Isaac of Accho, who had escaped the massacre that had ensued upon the capture of that city, arrived in Spain, and saw the Zohar, he was staggered, and became desirous of coming to the root of the question, whether this alleged ancient Palestinian work was really genuine, as he had been born and educated in the Holy Land, had associated with Nachmani's pupils, and yet had never heard a syllable about it. When he met Moses de Leon in Valladolid, the latter took a solemn oath that he had in his house at Avila an old copy of the book from the hand of Simon bar Yochaï, and pledged himself to submit it to Isaac of Accho for examination. But Moses de Leon became ill on his journey home, and died in Arevalo (1305). The veil around the origin of the Zohar was wrapped still closer. Two influential men of Avila,
