"Once more, I ask all participants to think what great cooperation means. I quote an example given by the Teacher: Forces which act against each other are mutually destroyed. Forces which act along parallel lines in the same direction manifest the sum of these energies, and forces which act separately are weakened, according to the angle of their divergency.... This fundamental law of physics is also a fundamental law of cooperation. Therefore, straighten out your divergencies so that your forces move in the same direction. Consider the consequences of divergencies. In true cooperation, no one is belittled, and he can help the better who knows and sees more. The more ignorant a person or a nation is, the less cooperation is in evidence."
