In legends, they say that the rainbow is the bridge between heaven and earth.

Think how difficult it is to walk this bridge. Not only does it appear very seldom, but we cannot easily find it. It seems to be just at the horizon, but the more we go toward it, the more it eludes us. To find its end, to even stand at its base and contemplate the dizzying heights that must hover over its high arch is even more impossible. If we were to stumble upon that sacred path, could we be light enough and pure enough to walk its raindrop surface to the embraces of gods?

My companion says that he once saw a triple rainbow. What a rare sight indeed! Truly, the land where he saw it must have been blessed, and he was lucky to have such beauty revealed to him.

But then again how high must heaven be to need three insurmountable bridges?
