But the words are written a bit differently because Hebrew expresses the movement from the side of the Light, from the top down, while Aramaic expresses the movement from the bottom up, from the perspective of the Kli (vessel, desire) with regard to the Light. This is the reason that some Kabbalah books were written in Hebrew and some in Aramaic, and there are books in which both languages are used.
It all depends on what the author wanted to say, on which side he described the system, and how we should read it in the most convenient way. Just as we use different computer languages for different programs on our computer, so are the two languages used in order to express the wisdom of Kabbalah: Aramaic and Hebrew.
