In short, it is lightning, but it is a long time.

This sentence means that anyone who will eventually make a sound that will shake the world will have to go through a long period of silence to accumulate strength.

From: The Antichrist by the philosopher Nietzsche, the original text is as follows:

Whoever will shock the world in the end will be deeply silent for a long time. Whoever lights lightning lingers like a cloud for a long time. My time is not up yet. Some people are born after death.

The implication of these words is that there must be a long process of self-accumulation before achieving great things.

Extended data:

The antichrist looks like a work of religious history, and it is a study of the history and essence of Christianity. Nietzsche first describes the historical evolution from Judaism to Christianity, then reveals the essence of Christianity, and finally discusses how it conquered the Roman Empire from bottom to top and has been influencing modern times.

The Antichrist is Nietzsche's last work before he went crazy. It is not only an inquiry into the history and essence of Christianity, but also a profound philosophical work. An eternal question is the relationship between truth and belief. Although Nietzsche opposed Christianity, he did not oppose religion itself. The key point is that the purpose of religion is a form of gratitude, and people need a god only because they are grateful to themselves.
