"The revolutionary struggle of the proletariat and people of each country goes through different stages and has its own characteristics, but none can be independent of the general laws governing the development of world history. It is of great importance for a proletarian party leading the revolutionary struggle and formulating the revolutionary line and policies of its own country to adhere to the principle of integrating the universal truth of Marxism-Leninism with the concrete revolutionary practice of its own country. Only when the universal truth of Marxism-Leninism is skillfully integrated with the concrete revolutionary practice of one’s own country, can one make Marxism-Leninism take root, blossom and yield fruit in the country, and lead the revolution to victory."
