They were to meet the objection, how the Kabbala, so long unknown, and kept secret by the prudent Kabbalists--for they had hesitated to impart any of it in writing--how this mysterious wisdom could all at once come to light, and be revealed to every one's knowledge. The Zohar frequently uses the following excuse: As the time in which Simon bar Yochaï lived was especially meritorious and rich in grace, and as the Messianic period was near, the veil which had concealed the book so long could now be drawn aside. There are certainly very few compositions which have exercised so much influence as the Zohar, or which can be compared with it in regard to the remarkable nature of its contents and form. It is a book without beginning or end, of which it is unknown whether it once formed part of a whole, whether the extant portions originally belonged to it, or were added later, or whether at an earlier period more of it was in existence. It consists of three principal parts, with appendices and explanatory comments. The absence of form in this farrago made it possible for certain portions to be imitated. It is so easy and tempting to imitate its wild though sonorous style. Thus the forgery was counter-forged. It is not positively certain whether the Zohar is to be regarded as a running commentary to the Pentateuch, as a theosophic manual, or as a collection of Kabbalistic sermons. And its contents are just as curious, confused and chaotic as its form and external dress. The Zohar with its appendages in no wise develops a Kabbalistic system like Azriel's, neither does it unfold an idea like Abraham Abulafia, but plays with the Kabbalistic forms as with counters--with the En-Sof, with the number of the Sefiroth, with points and strokes, with vowels, accents, with the names of God and the transposition of their letters, as well as with the Biblical verses and Agadic sayings--casts them about in eternal repetition, and in this manner produces sheer absurdities. Occasionally it gives a faint suggestion of an idea, but in a trice it evaporates in feverish fancies, or dissolves in childish silliness.
