There are two kinds of truths: Universal Truth and Contextual Truth. Universal Truth can be recognized by a feeling of peace or joy, it is timeless and always grounded in love. If something is Universally True it can be found in every philosophy, religion and culture, as well as in science. 

Contextual Truth is something that was true at one time or in the context of a certain situation, but does not apply Universally. It may bring up feelings of fear, anger, confusion or mistrust and may begin to have a limiting effect on our lives.
