To seek the truth constantly, even if you think you have the truth, you must always know in your heart, that you only have part of the truth. But it is true for you at the moment, and that is all that counts. So there is always truth in untruth, and untruth in truth. If you can always be aware of that, you will stop arguing. There is no such thing as a lie.
Lies are nothing more than energy flowing in a circle, spiraling back to where they came from.
If you say a lie today, tomorrow the lie will come true. If you wake up in the morning and say to the world I am ill, because you don't feel good. Then the truth is you are ill. But again, this is only a partial truth. There is truth in the statement, yet it is not entirely the truth.
