Kabbalists who revealed the Creator, wrote books about this, starting from Adam, the first person to attain the Creator, through Baal HaSulam. There are many Kabbalistic books mentioned in The Book of Zohar, which we aren’t familiar with. Apparently, these books have been lost. All the books written by sages from the nation of Israel up to HaShla HaKadosh (17th Century) were written from spiritual attainment.
Later, as a result of the descent of the level of the generations from the 17th Century on, not all authors of books on Kabbalah were in spiritual attainment. For this reason, a question arises regarding the authenticity of some books. We have at our disposal hundreds of books by authentic Kabbalists who wrote them while they were in our world and simultaneously had the perception of the spiritual world, a connection with the Creator. Hence, they were able to transmit their attainments to us in the form of texts, so that we, in turn, would obtain contact with what they attained.
However, The Book of Zohar is the only authentic Kabbalistic book about which it is written that through it we will come out of exile and rise to the level of those Kabbalists – the authors of these books. Indeed, The Book of Zohar truly has a special Light. The fact that there are other books, through which we can acquire a greater impression or understanding, is irrelevant when actually attaining the level of connection with the Creator.
There are many Kabbalistic texts, such as: “The Tree of Life” by the ARI, the Tanakh, the Gemara, and the Mishna, which are written in a rational, logical language that we understand. In contrast, when we read The Book of Zohar, we don’t understand what is written. It carries us into various directions. However, the special connection that it creates between our souls, between us who are beginning this path, and the source of Light that is able to correct us – is not present in any other book.
Therefore, of all the books, only about The Book of Zohar is it written that due to it we can come out of exile, to deliverance, and reveal the Creator. Other Kabbalistic sources also contain a connection, since the Kabbalists writing them possessed spiritual attainment. Their connection is expressed in their compositions. Nonetheless, only The Book of Zohar, can help us.
