My personal philosophy is to accept wisdom WHEREVER you can get it but I'm terribly paranoid and think everyone has an agenda and most people do, but my main question is in this world where you have to unlearn EVERYTHING you're fed in school how do you know who's "truth" is accurate? Don't let me down ya'll let's get a discussion/debate going.
In my honest opinion, truth is thrown around, but in my research most the time truth is what you accept as truth and deals with the mind. Truth is agreed upon or what is accepted as true. The only person that can accept truth and really know what is truthful is you, you are the smartest person you'll ever come across. Like the sister said, the gut feeling, inner voice is the way, trust self and go with instinct over what society has programmed in you. You'll see once you start listening to that inner voice, you'll learn and accept things that will help you a long your path. This is why people are so set on giving you some truth because it deals with the mind. The mind (subconscious) in all its power will manifest what it accepts as true, government is empowered through this and they know this.
Phuck being paranoid, just realize that you are a powerful being, people should be paranoid of you, not you of them, especially the government, why do you think they don't want you to discover self! We fear them while they fear us, lol. I do agree people usually have their own agendas, but so. Who cares, you have your own agenda to, and thats doing what you need to get done and keep it movin.
So to answer your question fully, no one's truth is completely accurate for you, only yours for you. Like Delber Blair says "there is no truth until you decide what is truth". This is just my opinion and is not law.
