春にエネルギーが吹き上がる、
 とすれば、
 秋にはエネルギー吹き下がる、
 そんなようなイメージ感を描いたもの。

 A cloud does not know why it moves in just such a direction and at such a speed, it feels an impulsion.... this is the place to go now.

But the sky knows the reason and the patterns behind all clouds, and you will know, too, when you lift yourself high enough to see beyond horizons...
(from "illusions, The Adventure of a Reluctant Messiah")
