What is the purpose of finding truth? Is it important to find truth, if so why? Is universal truth or individual truth the most important? How does truth and belief work together or separate? Is truth dependent or independent on anything?
Generally it is other way round. You keep on looking, unless truth wants to come before you, no matter what you do, you end up just keep on looking for it. Now how to make sure that what you got is truth or not. Simple- you give it a test- whatever it is does it change or does it not. If it change it cannot be truth and if it is persistent no matter what happens - it is truth. Just don't go by what book says, it is you who can get truth for yourself. Everyone can just show you direction, you have to travel the way on your own.
