病態: byôtai. Sickness and diseases (including, of course, pandemics) are unpleasant realities, but the renku poet should, in the words of William Butler Yeats, "cast a cold eye" on them. As with war, this is a category that you should avoid in the Introduction and Enlightenment sections of a renku. Visit this area of experience only in the middle (Body) section: in a 20-verse renku, verses 5-16.
