Realize this! There is no such thing as perfection. No thing is perfect. No one is perfect. No situation is perfect. We can begin to see things as they are once we let go of our ideals. Human beings are inherently flawed, things breakdown and s!@#$ happens.
There is actually only one true perfection and that is love. Love allows you to see people for who they are. Love allows you to see things as they are. Love allows you to accept the situation as it is.
O Sensei said that Aikido is love. I think what O Sensei was really talking about is that as we give ourselves to others when we take ukemi and that is love because we are sacrificing ourselves for another person's benefit. However, what is the truest expression of love is that the nage knows that the uke is sacrificing himself and that the nage not only appreciates it but also sacrifices himself by letting go of his desire to hurt the uke thus love comes full circle.
The enso or circle calligraphy above symbolizes emptiness and it is supposed to represent the calligrapher's level of enlightenment. The funny thing about an enso is that the more "enlightened" a person is supposed to be, the more imperfect the circle seems. Perfection is not realized but moreover it is the realization that perfection does not exist is the truest expression of love and thus perfection.
