Hello everyone,

Could you please tell me what "when all was brought to winter" means in the following context:

The lightworkers of the later generations found they simply could not neutralize the intention of the insipid dark warriors, who were so exceptionally focused and manipulating that the entire culture slipped, almost unknowingly, into the dark chasm of their secret rule.

With time, the pendulum swung so completely into the shadows that the only possibility for Earth—and the human race— was to bring it all down and start anew. That was the time of the Last Generation, the apex point of the third cycle of Atlantis, ***when all was brought to winter***: to rest and to be cleansed there, in the deep waters of your collective experience.

When you understand the cyclical nature of all life in the material realms, you realize that such events are a natural process and that this has been the way of Earth's immortality. There is a certain comfort in knowing that all energies eventually move towards center, where the fury of opposition transforms into the serenity of balance point. All things reach their peak, crash, and come up again, at the meridian.

Does the phrase mean "everything on Earth was destroyed"?

Thank you.
