The study of the book of the Zohar is a great help to purify and to bring sanctity to the soul and even if one doesn’t know what he’s saying and makes many mistakes while reading, it is of great importance to the Holy One Blessed Be He. And we see that in regards to the study of the Mishna there are many opinions that say that one must understand what he is studying, but when reading Tehillim (Book of Psalms) or the Zohar even if one doesn’t understand anything at all, it is important and received and desired by The Holy One Blessed Be He.
(Pele Yoetz, Zohar)
