There is only one Truth, but whose is it anyways??
All faith is false, all faith is true
Truth is the shattered mirror strown
In myriad bits; while each believes
His little bit the whole to own
~ Richard Francis Burton
As a person my opinion is simply my opinion. I can empathise and try to understand and feel what it’s like for someone else, but although I can come close, I can never know for sure exactly how a person is experiencing the world. I hold my own piece of mirror, and they hold theirs. Over time those experiences can get blurred and become less clear, meaning it can be difficult to remember the truth of exactly what happened. However most important is how one respond to the memories one do have, and how it affects their life now.
Once we accept that truth is not this fixed thing to be found and clung onto, it becomes easier to accept that others hold different truths, and that no matter how much we may disagree with them, no-one has a monopoly on the truth. For us as individuals it also gives space for hope that some of the negative truths we cling to may not be so fixed. A person might firmly hold the belief that they must never feel sad, as letting in even a bit of sadness would open the floodgates leading to an overwhelming wave of sadness descending upon them.
