Very good parable with are deep sense. Though it is called - “As water”, but an essence here at all in water has changed. Read and write please in comments as you have understood it.

Once Hyzyr, teacher of  Moses, has addressed to mankind with caution.

— There will come such day, — he has told, — when all water in the world, except that that will be specially collected, will disappear. Then on change to it there will be other water, and people will descend from it from mind.
