Something you decided automatically?
I don't see it as a decision.
I experiences jesus. I know buddhism is the truth. I dont practice either anymore. Truth isnt reflected on bible, sutras, jesus, mind. Its deeper than an external view of god. I found this through the arts.
Was it a personal experience that singled out one truth? Do you see the other beliefs as lies?
Personal experience isn't what determines truth. One 'singles' out the truth via rejecting falsehoods through observation and testing of hypotheses.
Beliefs, as in opinions, are not true nor false. On the other hand, those beliefs that are counter to observation are simply false.
Lies are statements that are deliberately false. A person isn't telling a lie, in my opinion, when they are stating a falsehood that they truly believe to be true. They are, in that case, simply mistaken.
