On the Lost Book of the Speculation
“What is surprising in this text is that it constitutes an irruption of Neoplatonic language and concepts into older cosmological and Merkabah teachings, as far removed from the language of the Bahir as it is from that of Isaac the Blind.
The few extant pages appear to have been carelessly thrown together without any sense of structure, and the exposition is in part erratic and opaque. The book is written in a pure Hebrew and in a curiously enthusiastic style. The long superscription says:
“ … The “Book of the Speculation” of the great master Rab Hammai, chief of those who speak of the subject of the inner [hidden] sefiroth, and he unveiled in it the essence of the whole reality of the hidden glory, whose reality and nature no creature can comprehend, [and of all that] in a truthful manner, such as it [the hidden kabhod?] is in the indistinct unity, in the perfection of which the higher and the lower are united, and it [this kabhod] is the foundation of all that is hidden and manifest, and from it goes forth all that is emanated from the wondrous unity. And Rab Hammai has interpreted these subjects according to the method of the doctrine of the Merkabah—’al derekh ma- ‘aseh merkabah—and commented upon the prophecy of Ezekiel.”
The language used in this superscription, as well as in the beginning of the work, is purely speculative. The notion of indistinct unity (‘ahduth shawah) is unknown in prekabbalistic Hebrew texts. The term, as becomes quite clear in the writings of Azriel of Gerona, refers to that unity in which all oppositions become “equal,” that is, identical.
This concept, and the idea of a coincidentia oppositorum in God and the highest sefiroth—which subsequently plays such an important role, particularly in Azriel—seems to appear here for the first time. According to Azriel, God is …
“ … the One who is united in all of His powers, as the fire’s flame is united in its colors, and His powers emanate from His unity as the light of the eyes proceeds from the black of the eye, and they are all emanated from one another like perfume from perfume and light from light, for one emanates from the other, and the power of the emanator is in the emanated, without the emanator suffering any loss.”
