Full context:   In this symbol the two water droplets swirl and mixing to represent its two intertransformative forms moving from turbid murky yin to the pure clear yang and back again. The two droplets are opposite in direction to each other to show that as one increases the other decreases but at the same time are equal in volume and substance denoting a state of dynamic tension. The dot of the opposite field in the droplets shows that they are infinitely divisible depicting there is always yin within yang and always yang within yin and the S- curve through the centre representative of the amount of yin or yang that is present when night turns to day. By drawing a horizontal and vertical line forming a cross directly through its centre will give the observation of the quantities of yin and yang that are present in all four seasons of the year on this planet.
