When a lie is believed our behavior is controlled by the liar.
But once truth is revealed, truth proves us to have been a fool .
Why not investigate fully what could be the truth before the truth proves you to have been a fool?
Yes, sometimes we can be mistaken. But even a mistake when it is believed will result in behavior actions which identify that we are not paying attention to what is in truth.
Thus we become a slave to the lie and must do what the lie inherently suggests we must do.
We have no alternative but to become the servant of the liar when we believe his lies.
Our response emotions become triggered within our subconscious mind and we end up believing even more lies about ourselves and others. Our day can become one of those bad days of life. Eventually many a person succumbs to living by habituated emotional responses and develops emotional disorders. The DSM is filled with just such multitude of developed mental and emotional health issues.
