Question: What state must a person reach when the convention opens? What must he experience?
Answer: He must feel that it is as if he has entered into a blender within which he wants to mix his thoughts and feelings with the thoughts and feelings of others, so that he has nothing left.
From this mixture of desires in the heart and thoughts in the mind, something emerges that can be called a “spiritual Kli,” a “spiritual Partzuf.” This is because a desire is the “body” of the “Partzuf,” and the thoughts are its “head.” In this way we create a pattern (model) of an Adam (one person), a single image of all of humanity.
The role of each one is to mix with everyone so there is nothing left of him, neither in the head nor in the heart. And what results will fill his heart and mind.
