1. "Cooperation must be accepted as the foundation of Existence." [AUM, 424]
2. "The Teaching considers the whole World as a Single World Community. We are instructed to develop a sense of cooperation, solidarity and friendliness, but bodily pushing is not commanded anywhere.

Every equation inevitably dissolves talent into insignificance, which leads to a loss of culture and a decrease in the level of civilization, that is, to a debauchery and, alas, to the next stage of debauchery, namely to coarsening. Therefore, Community and cooperation must be understood broadly and vitally. It is new scientific discoveries and life itself that will prompt new forms of cooperation." [Letters of Helena Roerich in 9 Volumes - 4. 109]

8. "The development of humanity is now at a level that summons all to cooperation, because the basis of Be-ness is sensible cooperation and cognition of psychic energy, without which mankind will be thrown into chaos. External accomplishments will not save man from self-destruction. …Proper education can ward off the danger of savagery." [Supermundane, 719]
9. "Each domain of life has become so complicated that cooperation everywhere is required. Not a single branch of labor can be named in which a man can regard himself as an isolated unit. Therefore cooperation becomes, as it were, the science of life. ... In each school subject the inherent possibility of cooperation should be pointed out precisely. ... Thought must be thus cultivated in order to sense the utmost useful application above and beyond conventionality. Some may not comprehend what relationship the cultivation of thinking has to the laws of cooperation, but cooperation is the harmony of humanity." [AUM, 423]

[Fiery World II, 350]

17. "People do not realize that when they are united their energy is increased many times." [Supermundane, 385]
18. " Forces acting in direct opposition to each other are mutually annihilative. Forces acting in parallel and in the same direction are effective in their sum total and forces acting in opposition are decreased in proportion to the angle of divergence. Why cannot people acknowledge that this fundamental law of physics is also a fundamental law of cooperation!" [Infinity II, 433]
19. "A nucleus of two or three friends, co-workers, can manifest the strongest support for great works." [Fiery World III, 80]
20. "Unity is indicated in all beliefs as the only bulwark of prosperity. It is possible to approve the best achievement if there is confidence in the unity of employees.

25. "The more ignorant a person or a nation is, the less cooperation there is in it." [Letters of Helena Roerich in 9 Volumes - 1. 071]
