Question: How is a congress related to the idea of a form clothed in matter? Isn’t it an illusion of this world?
Answer: A congress is the means with the help of which we wish to create an enormous, powerful desire (Kli, vessel). All who are part of this Kli will take pleasure in the Light that will be revealed in it. To take pleasure means to use this Light for correction.
What is a congress? A congress is the creation of the system where all parts are connected with each other. We hope that we will create such a connection between us, and in it, there, we will discover equivalence to the Light, the Creator. Every person will feel it to the extent of their being connected to this Kli, and that will become his spiritual revelation.
Creation of this collective Kli depends on everybody. It also depends on how well everyone is incorporated into the collective Kli because later, every person receives the sensation of the revealed Light depending on his measure of personal participation.
Everyone benefits from the collective desire inasmuch as they participate in it. This is the law of interaction between an individual and the group, and it is a real action.
