KnowLedge in itself is Eternal as it exists independent of the mind that emerges having evolved enough sophistication to have such capacity requisite to contemplate and hence comprehend this eternal knowledge. Knowledge is not merely information, it is information that has been collected by intelligent beings historically that is condensed and distilled within the crucible of conscious reason into dewdrops or pearls of meaningful wisdom. In each ephemeral moment awaits the possibility of discovery, of finding out by honest and diligent inquiry what the ancients knew, and it is the mark of a spiritually bereft fool to erroneously yet persistently assume the wisdom of the dead is of no serious consequence or concern. 
AS the dead are always with us, they live on in us, we who abandon the lessons of the past, even still - accursed by the mockery of the living, who know they shall never die. For real Immortality there exists also imitation-immortality. If the baseless substratum of what IS is infinite in possibility of what manifestations can grow into being, then there must also be included within the spectrum of possibility the possibility of transcending the spectrum of possibility itself. So there is possible a process of existence that transcends the total energetic manifesting process of existence. 
There must exist a true Immortality for there to have been any proliferation of imitations (gimmicks) of such Immortality. The truth really does exist as self-evidently proven by the existence of such things as lies - for what is a lie but an imitation-truth? For there to be the possibility of being nonplussed, hopelessly hypnotized and bamboozled; this is the perfect case there exists at least a thing that is not a lie, which what the truth is I can never in the remotest possibility say, but what is a lie i know in an instant. 
To the degree lies are spelled out to others, what goes around comes inevitably around again as per the self-evident law of action and simultaneous inescapable attendancy of consequences, which will always circle back eventually, how soon or when one never knows, although it is perfectly wise to know it shall, and thus of course to act in accordance with this realization of the only Truth there is, which is choice. 
There is no mistake save for one, which is not to learn from mistakes. That is the only true Mistake; all other mistakes are imitation-mistakes, and therefore not serious mistakes. Resolution of a mistake depends entirely on transformation of one's mental organizing principle, the mind, the lenzing perspective through which you blindly see and by which fool not only yourself dangerously enough, but all those also that come bounding hopelessly into contact with you, as the perfect charlatan doesn't know his own hoax; this the trick you have eternally played on yourself and forever will because you just can't help it.
