I would guess that the Winter Solstice is important because it combines a moment of poise and stillness--that only the dark can provide--with a real change of direction. Everything goes on but nothing is quite the same again. This echoes our experience of those Solstice moments of life: birth, menarche, leaving home and cleaving to another, death.... Womb moments.
To listen or be truly touched we have to be brought to the point of stillness. Only then can we be truly open to the other. Then we must enter the creative dark where all seems confused and uncertain and anything can happen. Then the light rises. Then all seems the same but there is that deep awareness that things will never be the same again.
