There are two main systems of the Cabbalah,—the system of Rabbi Moses Kordovero, and that of Rabbi Isaac Luria.[27] The former is more real, that is, it approximates more closely to reason. The latter, on the other hand, is more formal, that is, it is completer in the structure of its system. The modern Cabbalists prefer the latter, because they hold that only to be genuine Cabbalah, in which there is no rational meaning. The principal work of Rabbi Moses Kordovero is the Pardes (Paradise). Of Rabbi Isaac Luria himself we have some disconnected writings; but his pupil, Rabbi Chajim Vitall, wrote a large work under the title, Ez Chajim (The Tree of Life), in which the whole system of his master is contained. This work is held by the Jews to be so sacred, that they do not allow it to be committed to print. Naturally, I had more taste for the Cabbalah of Rabbi Moses than for that of Rabbi Isaac, but durst not give utterance to my opinion on this point.

After this digression on the Cabbalah in general, I return to my story. I learned that the under-rabbi or preacher of the place was an adept in the Cabbalah; and therefore, to attain my object, I made his acquaintance. I took my seat beside him in the synagogue, and as I observed once that after prayer he always read from a small book, and then put it past carefully in its place, I became very curious to know what sort of book this was. Accordingly, after the preacher had gone home, I went and took the book from the place where he had put it; and when I found that it was a Cabbalistic work, I went with it and hid myself in a corner of the synagogue, till all the people had gone out and the door was locked. I then crept from my hiding-place, and, without a thought about eating or drinking the whole day long, read the fascinating book till the doorkeeper came and opened the synagogue again in the evening.

Shaarei Kedushah, or The Gates of Righteousness, was the title of this book; and, leaving out of account what was visionary and exaggerated, it contained the principal doctrines of psychology. I did with it therefore as the Talmudists say Rabbi Meïr acted, who had a heretic for his teacher, "He found a pomegranate; he ate the fruit and threw the peel away."[28]

In two or three days I had in this way finished the book; but instead of satisfying my curiosity, it only excited it the more. I wished to read more books of the same sort. But as I was too bashful to confess this to the preacher, I resolved to write him a letter, in which I expressed my irresistible longing for this sacred science, and therefore entreated him earnestly to assist me with books. I received from him a very favourable answer. He praised my zeal for the sacred science, and assured me that this zeal, amid so little encouragement, was an obvious sign that my soul was derived from Olam Aziloth (the world of the immediate divine influence), while the souls of mere Talmudists take their origin from Olam Jezirah (the world of the creation). He promised, therefore, to assist me with books as far as lay in his power. But as he himself was occupied mainly with this science, and required to have such books constantly at hand, he could not lend them to me, but gave me permission to study them in his house at my pleasure.

Who was gladder than I! I accepted the offer of the preacher with gratitude, scarcely ever left his house, and sat day and night over the Cabbalistic books. Two representations especially gave me the greatest trouble. One was the Tree, or the representation of the divine emanations in their manifold and intricate complexities. The other was God's Beard, in which the hairs are divided into numerous classes with something peculiar to each, and every hair is a separate channel of divine grace. With all my efforts I could not find in these representations any rational meaning.

My prolonged visits however were extremely inconvenient to the preacher. He had, a short time before, married a pretty young wife; and as his modest little house consisted of a single apartment, which was at once parlour, study, and bedroom, and as I sat in it at times reading the whole night, it happened not infrequently that my elevation above the sphere of sense came into collision with his sensibility. Consequently, he hit upon a good plan for getting rid of the incipient Cabbalist. He said to me one day, "I observe that it necessarily puts you to a great deal of inconvenience to spend your time constantly away from home for the sake of these books. You may take them home with you one by one if you please, and thus study them at your convenience."

To me nothing could be more welcome. I took home one book after another, and studied them till I believed that I had mastered the whole of the Cabbalah. I contented myself not merely with the knowledge of its principles and manifold systems, but sought also to make a proper use of these. There was not a passage to be met with in the Holy Scriptures or in the Talmud, the occult meaning of which I could not have unfolded, according to Cabbalistic principles, with the greatest readiness.

The book entitled Shaarei Orah[29] came to be of very good service here. In this book are enumerated the manifold names of the ten Sephiroth, which form the principal subject of the Talmud, so that a hundred or more names are given to each. In every word of a verse in the Bible, or of a passage in the Talmud, I found therefore the name of some Sephirah. But as I knew the attribute of every Sephirah, and its relation to the rest, I could easily bring out of the combination of names their conjoint effect.

To illustrate this by a brief example, I found in the book just mentioned, that the name Jehovah represents the six highest Sephiroth (not including the first three), or the person of the Godhead generis masculini, while the word Koh means the Shechinah or the person of the Godhead generis feminini, and the word amar denotes sexual union. The words, "Koh amar Jehova,"[30] therefore, I explained in the following way, "Jehovah unites with the Shechinah," and this is high Cabbalism. Accordingly, when I read this passage in the Bible, I thought nothing else, but that, when I uttered these words, and thought their occult meaning, an actual union of these divine spouses took place, from which the whole world had to expect a blessing. Who can restrain the excesses of imagination, when it is not guided by reason?
