My Answer: The language of Kabbalah is the language of bestowal. All four languages of Kabbalah (the languages of the Tanach, Halacha, Hagaddah, and Kabbalah) explain how to bestow. This is what you should be learning when reading all the books and explanations. You should always remember that everything you are reading and hearing is teaching you about bestowal.
Language is a program that you place inside you and set in motion. This program makes you think and want differently, and gives you a new attitude to the world. So, the language of Kabbalah is the language of bestowal.
