The spirit originated from the spirit of Yanji bomb created by him at an arsenal in a forest during the anti-Japanese armed struggle.

He inspirited the anti-Japanese fighters with the spirit of Yanji bomb.

After the liberation of the country the Korean people fully displayed the spirit of self-reliance in the Pothong river improvement project.

Addressing the starting ceremony of the project on May 21, Juche 35 (1946), he said the Korean people should finish the project by themselves, not hoping for others' help but overcoming all difficulties.

The Japanese imperialists failed to finish the project in ten years though they mobilized three million people. But Korean people successfully completed the huge project in nearly two months.

In the spirit of self-reliance they carried out the industrialization of the country in only 14 years and built the West Sea Barrage in five years under the leadership of the President.

It is also thanks to the spirit that the country launched satellites and built up a nuclear deterrent.
