They are saying that if life has a structure, a staff, a sensible scaffold, we hang our nonsense on it. And they are saying that broken parts add color and music to the staff of life.
Mythology is not a lie, mythology is poetry, it is metaphorical. It has been well said that mythology is the penultimate truth--penultimate because the ultimate cannot be put into words. It is beyond words. Beyond images, beyond that bounding rim of the Buddhist Wheel of Becoming. Mythology pitches the mind beyond that rim, to what can be known but not told.
