Answer: The structure of the Russian language is closer to Hebrew than other languages, at least closer than English, French, and German are.
My students who are living in Israel and in all parts of the world today learn Hebrew. Some of them know many words or speak and read in this language.
A person who studies the wisdom of Kabbalah cannot avoid knowing some Hebrew just as a musician cannot avoid knowing Italian or a doctor knowing Latin. All the great scientists who were involved with the wisdom of Kabbalah and even a science often knew a good level of Hebrew, because without it, one cannot enter into the depth of the wisdom of Kabbalah.
It is very important to know how to read in Hebrew. It is possible not to know the spoken language; the main thing is to know how to read Hebrew.
