Answer: We will work on this at the time of the conventions as well. To do this, we need to re-read the article “The Freedom” and Rabash’s articles about unification. We need to study again the shattering of the spiritual Kli (vessel), how it shaped our earthly perception of ourselves: We now see that we are distant from one another, existing in opposition to one another, in a growing egoism, hatred, and various egoistic desires.
We have to understand that our nature is made to be so opposite to the Creator on purpose, in order for us to rise above it specifically from contradiction, starting from the opposite state, and thus be able to sense Him, since otherwise we would be incapable of it. We begin to feel and build ourselves in similarity to Him specifically based on the contrast between our nature and His.
Hence the most important preparation is to repeat the material that we study all the time: a little bit from Kabbalah itself—about the shattering of the vessel and its correction, as well as the topic of the development of egoism from Adam till our days covered in one of the “Talks about a New Life.” In general, we have lots of materials on this subject.
But most important is to simply know why you come to the convention. You come there to participate in the general Kli, in the general desire, which we all created and in which we will sense the Creator.
