Two forces descend from the single source, the Creator. The force that pertains to Him is the force of love and bestowal. While the quality of reception, an “artificial” force made by the Creator, did not exist before the creation. These two forces exist as plus and minus between themselves in all of nature: from the Upper worlds to our world. They are completely opposite to each other in order that we, the negative force of egoism, reception, with the help of our qualities would be able to determine the force opposite to us, the Creator. And not only to determine this force, but to start interacting with Him.
