"Whoever thou mayest be, beloved stranger, whom I meet here for the first time, avail thyself of this happy hour and of the stillness around us, and above us, and let me tell thee something of the thought which has suddenly risen before me like a star which would fain shed down its rays upon thee and every one, as befits the nature of light. - Fellow man! Your whole life, like a sandglass, will always be reversed and will ever run out again, - a long minute of time will elapse until all those conditions out of which you were evolved return in the wheel of the cosmic process. And then you will find every pain and every pleasure, every friend and every enemy, every hope and every error, every blade of grass and every ray of sunshine once more, and the whole fabric of things which make up your life. This ring in which you are but a grain will glitter afresh forever. And in every one of these cycles of human life there will be one hour where, for the first time one man, and then many, will perceive the mighty thought of the eternal recurrence of all things:- and for mankind this is always the hour of Noon"

Even a thought experiment can unleash a burdensome doubt in the mind capable of inflicting anguish and altering one's life in a potentially negative way. We all seek certainty, and given that the Dhamma is one of the few paths which can be tried for oneself for the sake of proving its worth, and readily abandoned should its promises prove false, it seemed the logical choice as an attempt at a higher understanding. Perhaps the human mind is incapable of such an understanding, and it's all an attempt to climb the wall. I don't like the idea of being eternally fenced in whether it be the same thing or something entirely different. A cycle is a cycle is a cycle and as a being seemingly sustained by novelty it almost seems my nature to pursue such a path of release.

That a problem may exist is often enough of a problem to warrant a potential solution.
