The Magic Lakes - folk story

Long time ago I heard a story about The Magic Lakes.
No one really knows now where those lakes are,
Only a few people used to know the road to a pure blue water and evergreen grass.
Drink a bit, wash your face - will be instantly stronger, have of best and live longer, have the wisdom of all...
Bad people would give anything to find those roads, get the power without control, but they couldn't go alone.
They need a good person to swim to the middle of the lake and get a white flower from only clear blue water in one special night.
The Magic Lakes doesn't accept bad people.
And this is a story.
A man meet a woman, time was good and one time she asked if they go far, just together, look for a night lake to swim.
The water was cold, he had to go alone:
Just go to the middle and get a flower for me.
Don't look back, swim, I will wait...
