Man was created with "self-love," and where one does not see that an act will yield self-benefit, one has no motivation to make even a tiny movement. And without annulling self-love, it is impossible to achieve Dvekut (adhesion) with the Creator, meaning equivalence of form.
For this reason, society must consist of individuals who unanimously agree that they must achieve it. Then, all the individuals become one great force that can fight against itself, since everyone is integrated in everyone else. Thus, each person is founded on a great desire to achieve the goal.
To be integrated in one another, each person should annul himself before the others. This is done by each seeing the friends' merits and not their faults. But one who thinks that he is a little higher than the friends can no longer unite with them.
It is important to remain serious during the assembly, so as not to lose their intention for the aim of their gathering - to attain adhesion with the Creator.
Therefore, care should be taken safeguarding against frivolity, maintaining equality among them, so they may be annulled before the other.
