You can only be true at this moment here and now. The only reality is inside your body, everything else is projected through the sensory system as a subjective reality, meaning you only understand that which you have been subjected to. When one passes judgement onto something that they have not experienced then it is an opinion which is not true in reality and is an alternate reality created by the human ego of the self through fear of its own survival. It fears that if it is found out to 'not know,' then there is a possibility that truth will dominate. However, the human ego thinks that it is the truth of existence and that it possesses the answer to every question.
Notice how when someone says something or something occurs that we do not understand, our feelings and thoughts join together to take a position or construct an opinion. Eventually and automatically, two parties involved take positions which is where we form a stalemate, an argument or disagreement. This phenomena is a major cause for all distress and confusion.
WHEN YOU ACT UPON A FEELING YOU HAVE TAKEN A POSITION - THERE ARE NO EXCEPTIONS.
