There must become an iron wall between Torah and money.

Let's say that Rav Nahman was right that there is such a thing as תלמידי חכמים שדיים יהודאיים Torah scholars that are demons. They are especially set up to trick people into doing evil by means of supposedly teaching Torah. Then how does one guard oneself from them and also be sure not to become one himself? 

Obviously learning Torah is not an answer to this problem since that is the whole problem in the first place. And in the writings of Rav Nahman himself I do not recall any suggestion about this except for the only one in the LeM vol I perek 12.  There he explains the difference between a true Torah scholar and one who is from the Dark Side as being the difference of one who learns Torah for its own sake as opposed to those who learn for money and power. 

Now I know it is the custom to ignore the problem of using Torah to gain power and money , but I think the reason people minimize the problem is they do not realize the repercussions that are suggested y Rav Nahman. So as difficult of a solution it may be I think the only way to solve this problem is by ceasing to use Torah to make money. To simply stop the connection that exists that people that learn Torah think they will get support for doing so from the State or individual donors. There must become an iron wall between Torah and money. In this way the only people that will learn Torah will learn Torah for its own sake.
