Answer: Begin to think: There is one reason, one force, one desire, and the concept of “One” includes all of that. This attribute-force-thought dwells above us.
We attain it from below, from the separation between us, since otherwise, without the initial division into parts, it is impossible to attain the whole. You can’t speak about one without knowing what two are.
This is why we attain perfection from within a lack thereof. And then, as the Kli (vessel) or desire discovers an increasingly greater shattering, meaning separation from the others, as well as a greater number of differences between us and this One whole, we attain His unity more and more.
It is impossible to convey this feeling. A person doesn’t lose himself, but becomes included into a new level, that of the single Thought.
Try to describe this to yourselves. At least we are already able to talk about it a little. The more we try together, the faster we will reveal this. But this is the discovery of a real force. And then you feel everything that exists below it, in our world, like a children’s game, like something fictitious.
