Except for the title, I've no idea where that came from. I wasn't looking for it, it was a happy accident. Contrary to what Cliff Jones says, it's not a Waley translation.
Spring now sets.
Watch little by little the night turn around. On the road back, sunrise over Heng-t'ang. The blossoming of the morning star shines farewell on the jewelled saddle. Boundless the leaves roused by spring, Countless the twigs which tremble in the dawn. Whether the willow can love or not, Never a time when it does not dance.
