Learning Torah in English –Torah Stones versus Torah Bricks: 

Difference between stones and bricks in the letters of speech: There exist two different types of materials that can be used to build a house; one is stone and the second is brick. Stones are naturally grown while bricks are made by man. Likewise, in Torah there exist two forms of letters, one are the letters of Lashon Hakodesh which is the language that was used by G-d to give the Torah to Moshe on Sinai, and the second are the letters of the languages of all the other 70 nations of the world.  

Elevating the mundane languages: The Jewish people are scattered throughout all of the 70 nations, and through speaking the local language of these countries within their business dealings, and then going forward in serving G-d in prayer and study of Torah, they elevate the letters of speech of the 70 nations. These letters become elevated to the root of the soul of each individual. This is the spiritual building of bricks, and represents the mundane which is used for holy [i.e. Chulin Shenaseh Al Taharas Hakodesh]. These letters of the 70 foreign languages also become elevated when they are used to speak words of Torah to understand the Torah, as we see with regards to the Talmud that it was written in Aramaic. Now, just as bricks must be burned in an oven in order to become hard, so too, in order to be able to elevate the letters of the 70 foreign languages it is necessary for one to arouse the fire of love of G-d in the Shema prayer. This burns and incorporates all the letters that one spoke for his business dealings, as well as all the food and clothing that one consumes and uses, within G-dliness.
