In The Left Hand of Darkness the physiological state of dothe is described as being a temporary manifestation of great strength and stamina which normally leaves the individual exhausted when concluded. Dothe is normally somewhat brief but can be sustained by focus for longer periods, with commensurate weariness as a result.
What was not clear to me was how dothe relates to the other physiological characteristics of Gethenians; specifically the detailed description of their anatomic adaptations to androgyny and hermaphroditism?
Possible this was explained or alluded to in the book and I missed it, but without an explanation it seems like an unusual part of the story. Everything else seemed to have a tightly woven nature and clear purpose.
