(Q-A) Cloud and Rain
Answered by: Miroku
Ah, I am delighted you asked!
You see, when a man and a woman are both of certain age, they might want to make clouds and rain as a physical manifestation of their love. Or to procreate. Or just have some fun together.
So, as the jade dragon lifts its head from its slumber, its scales iron-hard, it peers to where the twin columns of polished ivory line the way to the heavenly gates of the coral palace of the sea king.
It sneaks in the palace and makes its lair there, like a tidal wave coming and going until it is ready to roar its mighty cry of completion. As it does so, in the wake of its movement, steam rises from both participants, forming clouds that condensate where the dragon's mane and scales rub against the velvety walls of its new lair.
Then, as the mighty dragon roars, the coral palace's walls trembling around it, The dragon gets submerged in the divine sake flooding the palace. The sake then joins with the seeds of life from the dragon's mouth and create the rain that has the power to make the land bear fruits.
There can be many variations of this, including the jade dragon making its lair in the stone palace, hidden in secrecy between the two mountains. Or an union of two heavens, where no dragon is required.
In any case the result should be the same - the divine flood of heavenly waters sweeping the participants to the most wonderful plane of existence better than the mundane world.
