This is the tent-pole of heaven, the shaman’s tree or the ash tree Yggdrasil. Or it may be a deity, K’uei, for instance, the one-legged dancing master who twirls on his single foot at the center of space to set the stars in motion, and time’s wheel turning. Or Siva, dancing the dance of creation. North is more than cold. Wherever winter nights are long and the Dipper wheels high in the sky, too high for setting, the sovereignty of time lies with neither sun nor moon: it dwells in the mysterious core about which time turns.
