Not specificly, but we tend to construct with our minds what we want, there are tendencys to move in directions we percieve to be positive. Thinking positively is positive but the buddists say that you must think both positively and negatively to balance.If you don't know negative you won't know positive.
Thank You *kiss* I think the budist have a really good handle on things but I dont I try to stay positive because the negative can swallow me up.
