אות - רצא

This is from an unpublished manuscript from Likutey Moharan :

It is written, “Increase knowledge, increase pain” (Ecclesiastes 1:18) .

In every generation, new diseases come into existence. This is a result of the increase in knowledge. Each new discovery [based on philosophical and atheistic knowledge] results in some new pain. These are the new diseases that have come into existence. May God protect us!
