Our main work is to rise above our thoughts and desires, to manage to separate from them, and to ascend to the height where we all exist together, where the soul is. There is only one soul in the world.
This is why it is written that before receiving the Torah, the sons of Israel had to abstain for three days. Each one was trying to rise above all their corporeal concerns, thoughts, desires, and calculations in order to dedicate themselves only to the higher goal.
It is very difficult and requires dedicated, meticulous work, similar to picking up tiny grains until we get all of them, one by one, and our egoistic calculations end, until useless thoughts and desires stop awakening in a person, which pull him in different directions. Then, he will be more or less ready to include himself in thoughts and desires of the environment.
This austerity and abstinence, the enormous effort a person makes to prepare himself, is not a simple thing. A person must break his ego, come out of himself, pull himself off his position with actual physical effort, and become physically included in others. Then, he has to try to lower his head and accept their spirit from them, which will influence him. He cannot allow any freedom to his thoughts because they can throw him back outside the limits of the society, the group.
A person must lower himself and force himself to concentrate so as to put everything under the power of the environment, in both the corporeal form and on the inside, spiritually, in thoughts, in the desire. He must lose himself! He must let that which exists in the environment influence him so that no heart or mind would remain within him, and the only thing controlling him would be whatever exists in the environment.
This is the first stage of preparation in becoming included in one another. If we are able to do this, we can begin to speak of the influence of the upper force, the power of the group.
The group is not the physical formation that we imagine; it is not a group of physical bodies. The inner force of the group will influence us together with the Light that Reforms that exists in the group, gives sanctity to everyone, and enables them to rise above themselves. Then in this ascent a person will begin to feel the general force that fills the universe, and he will be able to understand what was written.
For this reason, during our convention and at least three days before it (and we should begin to accustom ourselves to it today), the most important thing for us is to be above all foreign thoughts and calculations and to limit ourselves to necessities that leave us no choice. Act through faith above reason in every regard.
Especially during the last three days before the convention, we must begin a real attack, days of abstinence, both physical and in thoughts and desires, so that we have only one aspiration and feel the least amount of disturbances.
