Hokusai's most famous picture is a large wave that forms a yin to the yang of empty space?nature's yin and yang of life and death. According to Chinese philosophy all opposites that one experiences?health and sickness, wealth and poverty, power and submission?can be explained in reference to the temporary dominance of one principle over the other. All phenomena have within them the seeds of their opposite state and even though an opposite may not be seen to be present, no phenomenon is completely devoid of its opposite state. This is called presence in absence or as I see it we are all in a queue for the next big wave.
