The Universal Harmony records various wonders, and — Zhuangzi

The Universal Harmony records various wonders, and it says: "When the P'eng journeys to the southern darkness, the waters are roiled for three thousand li. He beats the whirlwind and rises ninety thousand li, setting off on the sixth month gale." Wavering heat, bits of dust, living things blowing each other about – the sky looks very blue. Is that its real color, or is it because it is so far away and has no end? When the bird looks down, all he sees is blue too.
