THE SHUIWUDAO 

I find it interesting that the Pisces zodiac sign bears a stunning resemblance to the Taijitu (yin-yang) of Taoism. As a Pisces, this comparison has a much deeper meaning to me. Out of pure speculation, I feel that the resemblance between the Pisces zodiac sign and the Taijitu is illustrative of the feeling that the mind although one thing is divided into two (maybe especially Pisces). These two parts are not necessarily good or bad ( as portrayed in cartoons as an angel or the devil haha) but two different ways of thinking and interpreting. Considering myself, this idea can be extended to the point where an individual feels like he or she shares two different personalities (sort of like a very mild form of bi-polarity) while still being one person.

I also noticed Pisces are always described as being indecisive or more positively as individuals who tend to make sense out of two polar opposite arguments of the same matter. This complements the Taijitu idea which illustrates that even within yin there is yang (vice versa).
