The Force is not so much Yin And Yang where you need some sort of equal measure of both. "Balance" is the key word and I can make a silly everyday occurance to illustrate. You are walking down the street, everything is peaceful and easy. The someone trips you and you break your face. That's the Darkside at work. Balance is not equal meaures of both, it is a matter of non-conflict that is upset when someone or something tries to take it from you.
